  [clang] Refactor target attribute mangling. (#81893)

Before this patch all of the 'target', 'target_version' and
'target_clones' attributes were sharing a common mangling logic across
different targets. However we would like to differenciate this logic,
therefore I have moved the default path to ABIInfo and provided
overrides for AArch64. This way we can resolve feature aliases without
affecting the name mangling. The PR #80540 demonstrates a motivating
case.
