  [AArch64] Add FEAT_PAuthLR assembler support

Add assembly/disassembly support for the new PAuthLR instructions
introduced in Armv9.5-A:

- AUTIASPPC/AUTIBSPPC
- PACIASPPC/PACIBSPPC
- PACNBIASPPC/PACNBIBSPPC
- RETAASPPC/RETABSPPC
- PACM

  -----------
  [AArch64] Codegen support for FEAT_PAuthLR

- Adds a new +pc option to -mbranch-protection that will enable
  the use of PC as a diversifier in PAC branch protection code.

- When +pauth-lr is enabled (-march=armv9.5a+pauth-lr) in combination
  with -mbranch-protection=pac-ret+pc, the new 9.5-a instructions
  (pacibsppc, retaasppc, etc) are used.
