[runtimes] Append `-nostd*++` flags only for Clang (#151930)
Append `-nostdlib++` and `-nostdinc++` flags to `CMAKE_REQUIRED_FLAGS`
only if we are actually building with Clang. These flags are also
passed to the C compiler, which is not allowed in GCC. Since CMake
implicitly performs some tests using the C compiler, this can lead
to incorrect check results. This should be safe, since FWIU we only
need them when bootstrapping Clang.
Even though we know that Clang supports these flags, we still need
to explicitly check if they work, as in some scenarios adding
`-nostdlib++` actually breaks the build. See PR #108357 for examples
of that.
Fixes #90332
