x86/kconfig: Add as-instr64 macro to properly evaluate AS_WRUSS
Some instructions are only available on the 64-bit architecture.
Bi-arch compilers that default to -m32 need the explicit -m64 option
to evaluate them properly.
Fixes: 18e66b695e78 ("x86/shstk: Add Kconfig option for shadow stack")
Closes: https://lore.kernel.org/all/20240612-as-instr-opt-wrussq-v2-1-bd950f7eead7@gmail.com/
