sme: Signal frame support

Teach gdb about the ZA/SSVE state on signal frames and how to restore
the contents of the registers.

There is a new ZA_MAGIC context that the Linux Kernel uses to communicate
the ZA register state to gdb.

The SVE_MAGIC context has also been adjusted to contain a flag indicating
whether it is a SVE or SSVE state.

Regression-tested on aarch64-linux Ubuntu 22.04/20.04.
