Fix MSVC compiler/linker flags. Turn off ccache for vcpkg builds (this is only relevant to MSVC, where ccache does not work yet.) Throw an error if CMAKE_BUILD_TYPE is not valid or does not match case exactly (to make comparisons simple.) Add SetCompilerLinkerFlags.cmake lib with the functions: add_compiler_flags() For each flag passed in, add it to CMAKE_CXX_FLAGS and CMAKE_C_FLAGS if not already present. Also clears all build-specific flag variables on every call, if using this functions you must set build-specific flags yourself. add_linker_flags() For each flag passed in, add it to CMAKE_(EXE|SHARED|MODULE|STATIC)_LINKER_FLAGS if not already present. Add remove_dupes() function to VbamFunctions.cmake from: https://stackoverflow.com/a/41416298/262458 This is used to remove duplicate flags in SetCompilerLinkerFlags.cmake described above. Use the new functions to set compiler and linker flags for MSVC. Signed-off-by: Rafael Kitover <rkitover@gmail.com>

[build] Add basic clang-cl support XAudio2 is disabled because the included header needs to be updated to be parseable by clang.
