[Driver,CodeGen] Report error when enabling 64-bit-only features on non-64-bit arch (#101151)
In front-end, now we detect for `-mapx-features=/-mapxf` and `-muintr`,
which is aligned with GCC

https://gcc.gnu.org/bugzilla/attachment.cgi?id=58698&action=diff

In backend, we just disable these 64-bit-only features silently, so that
there is no error for
`-march=native -m32` on APX-supported arch.
