Allow for Catch::Approx to be used in a constexpr context

This PR adds functionality to skip around ANSI escape sequences in catch_textflow so they do not contribute to line length and line wrapping code does not split escape sequences in the middle. I've implemented this by creating a AnsiSkippingString abstraction that has a bidirectional iterator that can skip around escape sequences while iterating. Additionally I refactored Column::const_iterator to be iterator-based rather than index-based so this abstraction is a simple drop-in for std::string.

Currently only color sequences are handled, other escape sequences are left unaffected.

Motivation: Text with ANSI color sequences gets messed up when being output by Catch2 #2833.

+## 3.6.0
+
+### Fixes
+* Fixed Windows ARM64 build by fixing the preprocessor condition guarding use `_umul128` intrinsic.
+* Fixed Windows ARM64EC build by removing intrinsic pragma it does not understand. (#2858)
+  * Why doesn't the x64-emulation build mode understand x64 pragmas? Don't ask me, ask the MSVC guys.
+* Fixed the JUnit reporter sometimes crashing when reporting a fatal error. (#1210, #2855)
+  * The binary will still exit, but through the original error, rather than secondary error inside the reporter.
+  * The underlying fix applies to all reporters, not just the JUnit one, but only JUnit was currently causing troubles.
+
+### Improvements
+* Disable `-Wnon-virtual-dtor` in Decomposer and Matchers (#2854)
+* `precision` in floating point stringmakers defaults to `max_digits10`.
+  * This means that floating point values will be printed with enough precision to disambiguate any two floats.
+* Column wrapping ignores ansi colour codes when calculating string width (#2833, #2849)
+  * This makes the output much more readable when the provided messages contain colour codes.
+
+### Miscellaneous
+* Conan support improvements
+  * `compatibility_cppstr` is set to False. (#2860)
+    * This means that Conan won't let you mix library and project with different C++ standard settings.
+  * The implementation library CMake target name through Conan is properly set to `Catch2::Catch2` (#2861)
+* `SelfTest` target can be built through Bazel (#2857)
+
+
+## 3.5.4
+
+### Fixes
+* Fixed potential compilation error when asked to generate random integers whose type did not match `std::(u)int*_t`.
+  * This manifested itself when generating random `size_t`s on MacOS
+* Added missing outlined destructor causing `Wdelete-incomplete` when compiling against libstdc++ in C++23 mode (#2852)
+* Fixed regression where decomposing assertion with const instance of `std::foo_ordering` would not compile
+
+### Improvements
+* Reintroduced support for GCC 5 and 6 (#2836)
+  * As with VS2017, if they start causing trouble again, they will be dropped again.
+* Added workaround for targetting newest MacOS (Sonoma) using GCC (#2837, #2839)
+* `CATCH_CONFIG_DEFAULT_REPORTER` can now be an arbitrary reporter spec
+  * Previously it could only be a plain reporter name, so it was impossible to compile in custom arguments to the reporter.
+* Improved performance of generating 64bit random integers by 20+%
+
+### Miscellaneous
+* Significantly improved Conan in-tree recipe (#2831)
+* `DL_PATHS` in `catch_discover_tests` now supports multiple arguments (#2852, #2736)
+* Fixed preprocessor logic for checking whether we expect reproducible floating point results in tests.
+* Improved the floating point tests structure to avoid `Wunused` when the reproducibility tests are disabled (#2845)
+
+
+## 3.5.3
+
+### Fixes
+* Fixed OOB access when computing filename tag (from the `-#` flag) for file without extension (#2798)
+* Fixed the linking against `log` on Android to be `PRIVATE` (#2815)
+* Fixed `Wuseless-cast` in benchmarking internals (#2823)
+
+### Improvements
+* Restored compatibility with VS2017 (#2792, #2822)
+  * The baseline for Catch2 is still C++14 with some reasonable workarounds for specific compilers, so if VS2017 starts acting up again, the support will be dropped again.
+* Suppressed clang-tidy's `bugprone-chained-comparison` in assertions (#2801)
+* Improved the static analysis mode to evaluate arguments to `TEST_CASE` and `SECTION` (#2817)
+  * Clang-tidy should no longer warn about runtime arguments to these macros being unused in static analysis mode.
+  * Clang-tidy can warn on issues involved arguments to these macros.
+* Added support for literal-zero detectors based on `consteval` constructors
+  * This is required for compiling `REQUIRE((a <=> b) == 0)` against MSVC's stdlib.
+  * Sadly, MSVC still cannot compile this assertion as it does not implement C++20 correctly.
+  * You can use `clang-cl` with MSVC's stdlib instead.
+  * If for some godforsaken reasons you want to understand this better, read the two relevant commits: [`dc51386b9fd61f99ea9c660d01867e6ad489b403`](https://github.com/catchorg/Catch2/commit/dc51386b9fd61f99ea9c660d01867e6ad489b403), and [`0787132fc82a75e3fb255aa9484ca1dc1eff2a30`](https://github.com/catchorg/Catch2/commit/0787132fc82a75e3fb255aa9484ca1dc1eff2a30).
+
+### Miscellaneous
+* Disabled tests for FP random generator reproducibility on non-SSE2 x86 targets (#2796)
+* Modified the in-tree Conan recipe to support Conan 2 (#2805)
+
+
+## 3.5.2
+
+### Fixes
+* Fixed `-Wsubobject-linkage` in the Console reporter (#2794)
+* Fixed adding new CLI Options to lvalue parser using `|` (#2787)
+
+
+## 3.5.1
+
+### Improvements
+* Significantly improved performance of the CLI parsing.
+  * This includes the cost of preparing the CLI parser, so Catch2's binaries start much faster.
+
+### Miscellaneous
+* Added support for Bazel modules (#2781)
+* Added CMake option to disable the build reproducibility settings (#2785)
+* Added `log` library linking to the Meson build (#2784)

+/** \file
+ * Why does decomposing look the way it does:
+ *
+ * Conceptually, decomposing is simple. We change `REQUIRE( a == b )` into
+ * `Decomposer{} <= a == b`, so that `Decomposer{} <= a` is evaluated first,
+ * and our custom operator is used for `a == b`, because `a` is transformed
+ * into `ExprLhs<T&>` and then into `BinaryExpr<T&, U&>`.
+ *
+ * In practice, decomposing ends up a mess, because we have to support
+ * various fun things.
+ *
+ * 1) Types that are only comparable with literal 0, and they do this by
+ *    comparing against a magic type with pointer constructor and deleted
+ *    other constructors. Example: `REQUIRE((a <=> b) == 0)` in libstdc++
+ *
+ * 2) Types that are only comparable with literal 0, and they do this by
+ *    comparing against a magic type with consteval integer constructor.
+ *    Example: `REQUIRE((a <=> b) == 0)` in current MSVC STL.
+ *
+ * 3) Types that have no linkage, and so we cannot form a reference to
+ *    them. Example: some implementations of traits.
+ *
+ * 4) Starting with C++20, when the compiler sees `a == b`, it also uses
+ *    `b == a` when constructing the overload set. For us this means that
+ *    when the compiler handles `ExprLhs<T> == b`, it also tries to resolve
+ *    the overload set for `b == ExprLhs<T>`.
+ *
+ * To accomodate these use cases, decomposer ended up rather complex.
+ *
+ * 1) These types are handled by adding SFINAE overloads to our comparison
+ *    operators, checking whether `T == U` are comparable with the given
+ *    operator, and if not, whether T (or U) are comparable with literal 0.
+ *    If yes, the overload compares T (or U) with 0 literal inline in the
+ *    definition.
+ *
+ *    Note that for extra correctness, we check  that the other type is
+ *    either an `int` (literal 0 is captured as `int` by templates), or
+ *    a `long` (some platforms use 0L for `NULL` and we want to support
+ *    that for pointer comparisons).
+ *
+ * 2) For these types, `is_foo_comparable<T, int>` is true, but letting
+ *    them fall into the overload that actually does `T == int` causes
+ *    compilation error. Handling them requires that the decomposition
+ *    is `constexpr`, so that P2564R3 applies and the `consteval` from
+ *    their accompanying magic type is propagated through the `constexpr`
+ *    call stack.
+ *
+ *    However this is not enough to handle these types automatically,
+ *    because our default is to capture types by reference, to avoid
+ *    runtime copies. While these references cannot become dangling,
+ *    they outlive the constexpr context and thus the default capture
+ *    path cannot be actually constexpr.
+ *
+ *    The solution is to capture these types by value, by explicitly
+ *    specializing `Catch::capture_by_value` for them. Catch2 provides
+ *    specialization for `std::foo_ordering`s, but users can specialize
+ *    the trait for their own types as well.
+ *
+ * 3) If a type has no linkage, we also cannot capture it by reference.
+ *    The solution is once again to capture them by value. We handle
+ *    the common cases by using `std::is_arithmetic` as the default
+ *    for `Catch::capture_by_value`, but that is only a some-effort
+ *    heuristic. But as with 2), users can specialize `capture_by_value`
+ *    for their own types as needed.
+ *
+ * 4) To support C++20 and make the SFINAE on our decomposing operators
+ *    work, the SFINAE has to happen in return type, rather than in
+ *    a template type. This is due to our use of logical type traits
+ *    (`conjunction`/`disjunction`/`negation`), that we use to workaround
+ *    an issue in older (9-) versions of GCC. I still blame C++20 for
+ *    this, because without the comparison order switching, the logical
+ *    traits could still be used in template type.
+ *
+ * There are also other side concerns, e.g. supporting both `REQUIRE(a)`
+ * and `REQUIRE(a == b)`, or making `REQUIRE_THAT(a, IsEqual(b))` slot
+ * nicely into the same expression handling logic, but these are rather
+ * straightforward and add only a bit of complexity (e.g. common base
+ * class for decomposed expressions).
