cmake: c++ compiler flag exclusion, -Werror=implicit-int

Browse source 
Fixes: #28097

The compiler warning flag `-Werror=implicit-int` was added using
`set_compiler_property()` which will always add the compiler flag if the
compiler flag supports it.

This has been changed to `check_set_compiler_property()` which will
check if the flag is among the list of `CXX_EXCLUDED_OPTIONS`, and only
adds the flag if both the compiler supports it, and it is not an
excluded option.
