The restoring of TPIDR2 signal context has been broken since it was
merged, fix this and add a test case covering it. This is a result of
TPIDR2 context management following a different flow to any of the other
state that we provide and the fact that we don't expose TPIDR (which
follows the same pattern) to signals.
