Boyan Karatotev d21435e967 kselftests/arm64: add PAuth tests for single threaded consistency and differently initialized keys 
PAuth adds 5 different keys that can be used to sign addresses.

Add a test that verifies that the kernel initializes them to different
values and preserves them across context switches.
