Catch2-2-2.13.10-bp156.2.2

- Update to version 2.13.10:
  * Fixed issue with catch_discover_tests when there is multiple of
    256 tests (gh#catchorg/Catch2#2401, gh#catchorg/Catch2#2503).
  * Catch2-provided main and wmain are explicitly marked as __cdecl
    when compiled with MSVC (gh#catchorg/Catch2#2486,
    gh#catchorg/Catch2#2487).
  * Replaced deprecated std::aligned_storage
    (gh#catchorg/Catch2#2419, gh#catchorg/Catch2#2420).
- Minor rebase of fix-pragmas-old-gcc.patch to apply cleanly.

- Initial package:
  * Branch off from obs://devel:libraries:c_c++/Catch2 at version
    2.13.9 and rename src package to Catch2-2.
  * Catch2-2-devel: Add 'Provides: Catch2-devel = %{version}'
    and 'Conflicts: Catch2-devel >= 3'.
  * Drop CMAKE_RELEASE_TYPE=Release to use default
  'RelWithDebInfo' value from %cmake macro.
