infra: individual test executables (#1212)

* infra: individual test executables

We used have tests contained in a single executable. This was fine for
testing, but it would be more convient to separate tests into indivudal
modules so targeted changes could have targeted tests.

This change associates each test file with its own executable. We now
have 14 tests for GSL each of which testing a different component.

* revert -Wno-reserved-identifier

* Update tests/span_tests.cpp

* be sure to include build type in ctest command

* [VS] make sure we are building the correct configuration

* restore tests/span_tests.cpp

* fix build break after merge conflicts

* fix build break after merge conflicts #2

* another try at fixing a build break

* fix silly typo. build break pt 4

* Use file globbing for test sources instead of manual list (#1227)

* Initial plan

* Use file globbing for test sources instead of manual list

Replace the manually maintained list of test sources with file(GLOB) to
automatically discover all .cpp files in the tests directory, excluding
no_exception_ensure_tests.cpp which needs special compilation flags.

This approach:
- Automatically picks up new test files without CMake updates
- Still correctly excludes no_exception_ensure_tests.cpp
- Maintains the same test build configuration
- Works with both C++14 and C++20
