  Log Message:
  -----------
  [AArch64]SME2 Multi-single vector SVE Destructive 2 and 4 Registers

This patch adds the assembly/disassembly for the following instructions:
  ADD (to vector): Add replicated single vector to multi-vector with multi-vector result.
  SQDMULH (multiple and single vector): Multi-vector signed saturating doubling multiply high by vector.
for 2 and 4 ZA SVE registers.

The reference can be found here:

https://developer.arm.com/documentation/ddi0602/2022-09

It also adds more size for the multiple register tuple:
  ZZ_b_mul_r,  ZZ_h_mul_r,
  ZZZZ_b_mul_r,  ZZZZ_h_mul_r,
for 8 bits and 16 bits with 2 and 4 ZA registers.

Depends on: D135468
