Signal that our assembly is compliant with the GCS feature, if
the GCS feature is enabled in the compiler (available since Clang
18 and GCC 15) - this is enabled by -mbranch-protection=standard
with a new enough compiler.
GCS doesn't require any specific modifications to the assembly
code, but requires that all functions return to the expected call
address (checked through a shadow stack).
