FEAT_SME2 adds the ZT0 register, whose contents may need to be
preserved and restored on signal handler entry and exit. This is
done with a new ZT_MAGIC record. We forgot to implement support for
this in our linux-user code before enabling the SME2p1 emulation,
which meant that a signal handler using SME would corrupt the ZT0
register value, and code that attempted to unwind an exception from
inside a signal handler would not work.
Add the missing record handling.
