include/intrin: Don't define `__cpuid` and `__cpuidex` for GCC 11

GCC has `__cpuid` as a macro. GCC 11 has `__cpuidex` as a static inline
function taking the same arguments, but without any indicative macros.

Reference: https://github.com/gcc-mirror/gcc/blob/23855a176609fe8dda6abaf2b21846b4517966eb/gcc/config/i386/cpuid.h#L333
