AArch64: Read pauth registers
Initialise the pauth registers when creating a target description, and store
the regnum of the first pauth register.
Use ptrace to read the registers in the pauth feature.
Do not allow the registers to be written.
gdb/ChangeLog:
* aarch64-linux-nat.c (fetch_pauth_masks_from_thread): New
function.
(aarch64_linux_nat_target::fetch_registers): Read pauth registers.
* aarch64-tdep.c (aarch64_cannot_store_register): New function.
(aarch64_gdbarch_init): Add puth registers.
* aarch64-tdep.h (struct gdbarch_tdep): Add pauth features.
* arch/aarch64.h (AARCH64_PAUTH_DMASK_REGNUM): New define.
(AARCH64_PAUTH_CMASK_REGNUM): Likewise.
