  [PAC][Driver] Support ptrauth flags only on ARM64 Darwin

Most ptrauth flags are ABI-affecting, so they should not be exposed to
end users. Under certain conditions, some ptrauth driver flags are intended
to be used for ARM64 Darwin, so allow them in this case.

Leave `-faarch64-jump-table-hardening` available for all AArch64 targets
since it's not ABI-affecting.
