Add support for pointer authentication
The previous commit added the infrastructure to load and save ARMv8.3-PAuth registers during Non-secure <-> Secure world switches, but didn't actually enable pointer authentication in the firmware. This patch adds the functionality needed for platforms to provide authentication keys for the firmware, and a new option (ENABLE_PAUTH) to enable pointer authentication in the firmware itself. This option is disabled by default, and it requires CTX_INCLUDE_PAUTH_REGS to be enabled.
