[Clang][ARM][AArch64] Add support for Armv9-A, Armv9.1-A and Armv9.2-A
armv9-a, armv9.1-a and armv9.2-a can be targeted using the -march option both in ARM and AArch64. - Armv9-A maps to Armv8.5-A. - Armv9.1-A maps to Armv8.6-A. - Armv9.2-A maps to Armv8.7-A. - The SVE2 extension is enabled by default on these architectures. - The cryptographic extensions are disabled by default on these architectures. The Armv9-A architecture is described in the Arm® Architecture Reference Manual Supplement Armv9, for Armv9-A architecture profile (https://developer.arm.com/documentation/ddi0608/latest). Reviewed By: SjoerdMeijer Differential Revision: https://reviews.llvm.org/D109517
