Normalize ptrauth handling in sanitizer runtime (#100483)
1. Include `ptrauth.h` if `ptrauth_intrinsics` language feature is specified (per ptrauth spec, this is what enables `ptrauh.h` usage and functions like `ptrauth_strip`)
2. For PAC-RET fallback implement two changes:
1. Switch to macro, so we can ignore key argument
2. Ensure the unsigned value is erased from LR, so the possibility of gadget reuse is reduced.
Fixes #100467
