Clang: Support Windows variants for GNU and MSVC (#13035, #14458) Teach the compiler identification preprocessor tests to report when Clang simulates MSVC, and what version. If not MSVC, assume GNU. Teach compiler information modules Clang-(C|CXX) to recognize when Clang simulates MSVC and skip loading the GNU information. Teach the Windows-MSVC platform information to recognize when it is loaded as the simulated compiler and use that version information instead of the real compiler's (different) version scheme. Add platform modules Windows-Clang-(C|CXX) and support module Windows-Clang to load either Windows-MSVC or Windows-GNU and wrap the corresponding information macros.

Avoid if() quoted auto-dereference when checking for "MSVC" When testing CMAKE_<LANG>_COMPILER_ID values against "MSVC", do not allow the definition of the "MSVC" variable to be expanded.
