  [LLVM][AArch64] Add assembly/disassembly for FTMOPA and BFTMOPA (#113230)

This patch adds assembly/disassembly for the following SME2p2
instructions (part of the 2024 AArch64 ISA update)

      -  BFTMOPA (widening) - FEAT_SME2p2
      -  BFTMOPA (non-widening)  - FEAT_SME2p2 & FEAT_SME_B16B16
      -  FTMOPA (4-way) - FEAT_SME2p2 & FEAT_SME_F8F32
      -  FTMOPA (2-way, 8-to-16) - FEAT_SME2p2 & FEAT_SME_F8F16
      -  FTMOPA (2-way, 16-to-32) - FEAT_SME2p2
      -  FTMOPA (non-widening, f16) - FEAT_SME2p2 & FEAT_SME_F16F16
      -  FTMOPA (non-widening, f32) - FEAT_SME2p2

- Add new ZPR_K register class and ZK register operand
- Introduce assembler extension tests for the new sme2p2 feature
