Add test for pixel_reference_is_mutable metafunction. From the legacy tests - port value_core and reference_core fixtures, see https://lists.boost.org/boost-gil/2019/02/0138.php - port representative pixel types and verify with tests of some metafunctions. Clean up test names for CTest in the CMake configuration. Disable some GCC/clang warnings in tests to avoid CI build termination due to too long logs.
