The compiler option "-fdiagnostics-color=always" is not known to XCC
(which is based on really old GCC). So don't enable color
diagnostic output when building with XCC.

GCC 11 defaults to output DWARF version 5 which pyelftools cannot
currently parse. So keep output at version 4 for the time being.

Adds no-threadsafe-statics to compiler flags for gcc and arcmwdt.
The flag is required to compile the samples - the module can compile
without it.

When compiler results are piped through a non-terminal (e.g. ninja)
the compiler disables colour diagnostics. Using `-fdiagnostics-color`
forces the compiler to enable colour output. This flag is set for
clang and gcc when `ZEPHYR_BUILD_COLOUR_DIAGNOSTIC` environment
variable is set when a clean build is started.

'-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.

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.
