  [AArch64][ARM] add Armv8.9-a/Armv9.4-a identifier support

For both ARM and AArch64 add support for specifying -march=armv8.9a/armv9.4a to
clang. Add backend plumbing like target parser and predicate support.

For a summary of Amv8.9/Armv9.4 features, see:

For detailed information, consult the Arm Architecture Reference Manual for
A-profile architecture:
