'-Wexpansion-to-defined'
Warn whenever 'defined' is encountered in the expansion of a macro
(including the case where the macro is expanded by an '#if'
directive). Such usage is not portable. This warning is also
enabled by '-Wpedantic' and '-Wextra'.
This is enabled by default in llvm but not in gcc. Given that it is 'not
portable', lets disallow this in gcc and keep both compilers in sync.

Compound assigments like x |= y to volatile qualified values are
deprecated in C++20. This idiom is common in CMSIS headers for
manipulating peripheral registers. Since these headers are core they
are likely to be included indirectly in C++ modules; since they are in
vendor-provided headers we can't "fix" them.
Disable the warning when building for C++.

XCC does not support the compiler flag -Wno-unused-but-set-variable
so check for flag support before setting it in cmake.

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.
