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)
+
