Clang: Use -fno-ansi-escape-codes for color diagnostics on Windows
-fno-ansi-escape-codes is used only on Windows by Clang.
Without the flag color diagnostics are displayed only if clang.exe
is executed directly. Build tools like ninja and mingw32-make
will not display colored diagnostics.
Using -fno-ansi-escape-codes will make the build tools pass
the colored diagnostics to the calling application e.g IDE.
Fixes: #24235
