aarch64: Add GCS support to longjmp
This implementations ensures that longjmp across different stacks
works: it scans for GCS cap token and switches GCS if necessary
then the target GCSPR is restored with a GCSPOPM loop once the
current GCSPR is on the same GCS.
This makes longjmp linear time in the number of jumped over stack
frames when GCS is enabled.
