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.
