aarch64: Add new target options for 2024 Architecture Extension and Armv9.6-A

This does not add support for these version (and the corresponding
__ARM_FEATURE_<X> macros aren't implemented for this reason) but
accepts the command line strings and allows these to be passed on to
the assembler.

Armv9.6-A is supported by the new "armv9.6-a" option and defined as
"armv9.5-a+cmpbr+lsui+occmo"

The new extensions are:

- fprcvt        (FEAT_FPRCVT)
- lsfe          (FEAT_LSFE)
- f8f32mm       (FEAT_F8F32MM)
- f8f16mm       (FEAT_F8F16MM)
- sme2p2        (FEAT_SME2p2)
- sve2p2        (FEAT_SVE2p2)
- sve-aes2      (FEAT_SVE_AES2)
- sve-f16f32mm  (FEAT_SVE_F16F32MM)
- sve-bfscale   (FEAT_SVE_BFSCALE)
- ssve-aes      (FEAT_SSVE_AES)
- lsui          (FEAT_LSUI)
- occmo         (FEAT_OCCMO)
- pcdphint      (FEAT_PCDPHINT)
- pops          (FEAT_PoPS)
- ssve-bitperm  (FEAT_SSVE_BitPerm)
- ssve-fexpa    (FEAT_SSVE_FEXPA)
- sme-mop4      (FEAT_SME_MOP4)
- sme-tmop      (FEAT_TMOP)
