AArch64: Use HWCAP to detect pauth feature
Add aarch64_get_hwcap functions for reading the HWCAP.
From this extract the PACA value and use this to enable pauth.

* aarch64-linux-nat.c
(aarch64_linux_nat_target::read_description): Read PACA hwcap.
* aarch64-linux-tdep.c
(aarch64_linux_core_read_description): Likewise.
(aarch64_linux_get_hwcap): New function.
* aarch64-linux-tdep.h (AARCH64_HWCAP_PACA): New define.
(aarch64_linux_get_hwcap): New declaration.
gdb/gdbserver/ChangeLog:
