Ahmed Bougacha 5f1bb62c6b [AArch64][PAC] Lower ptrauth constants in code for MachO. (#97665) ...

This also adds support for auth stubs on MachO using __DATA,__auth_ptr.

Some of the machinery for auth stubs is already implemented;  this
generalizes that a bit to support MachO, and moves some of the shared
logic into MMIImpls.

In particular, this originally had an AuthStubInfo struct, but we no
longer need it beyond a single MCExpr.  So this provides variants of
the symbol stub helper type declarations and functions for "expr
stubs", where a stub points at an arbitrary MCExpr, rather than
a simple MCSymbol (and a bit).
