- Support for pac-ret on aarch64 existed partially before inside the
DWARF parser but this needed applying elsewhere in the code
- Move PAC mask stripping functions to be accessible from more places
and rename to `tdep_ptrauth_insn_mask` for consistency with the
corresponding accessor function
- Apply PAC stripping in appropriate places
- Add ptrace accessor function implementation for `ptrauth_insn_mask`
- make check is now passing on aarch64 when compiled with
`CFLAGS="-mbranch-protection=standard"`
- There is an extra function in the ptrace library ABI now
(`_UPT_ptrauth_insn_mask`) but there are also some other ABI changes
reported by libabigail / `make abi-check` that are unrelated to this
change, so I am not sure whether to proceed with updating the .abi
files or not
