[Clang][LLVM][AArch64]Add new feature SSVE-BitPerm (llvm#121947)
The 20204-12 ISA update release adds a new feature: FEAT_SSVE_BitPerm, which allows the sve-bitperm instructions to run in streaming mode. It also removes the requirement of FEAT_SVE2 for FEAT_SVE_BitPerm. The sve2-bitperm feature is now an alias for sve-bitperm and sve2. A new feature flag sve-bitperm is added to reflect the change that the instructions under FEAT_SVE_BitPerm are supported if: on non streaming mode with FEAT_SVE2 and FEAT_SVE_BitPerm or in streaming mode with FEAT_SME and FEAT_SSVE_BitPerm
