Implement support for ZA in signal handling in a very similar way to how we implement support for SVE registers, using a signal context structure with optional register state after it. Where present this register state stores the ZA matrix as a series of horizontal vectors numbered from 0 to VL/8 in the endinanness independent format used for vectors.
As with SVE we do not allow changes in the vector length during signal return but we do allow ZA to be enabled or disabled.

This follows the SVE implementation closely. It looks fine to me:
