Guard color diagnostics opts by compiler type (#98952)
On Linux system where `/usr/bin/c++` is not a symlink to either `g++` or `clang++`, `try_compile` can still incorrectly identify `gcc` as supporting `-fcolor-diagnostics` flag.
Rather than introducing a super complex condition (i.e. `USE_CCACHE` and `LINUX` ...) just guard the checks specific to compiler identifier.
