Mark Brown 776b4a1cf3 arm64/sme: Add ptrace support for ZA
The ZA array can be read and written with the NT_ARM_ZA.  Similarly to
our interface for the SVE vector registers the regset consists of a
header with information on the current vector length followed by an
optional register data payload, represented as for signals as a series
of horizontal vectors from 0 to VL/8 in the endianness independent
format used for vectors.

On get if ZA is enabled then register data will be provided, otherwise
it will be omitted.  On set if register data is provided then ZA is
enabled and initialized using the provided data, otherwise it is
disabled.
