  -----------
  [AArch64] Make -march and target(arch=..) attributes imply dependent features

Specifying an architecture revision should also add feature strings for
any dependent default extensions. Otherwise the new checks for
target-dependent features for acle intrinsics from D134353 and D132034
can fail.

This patch does that in setFeatureEnabled, similar to the addition of
dependent architecture revisions. +sve also needs to be added to armv9
architectures in the target parser, as it is implied by +sve2.

Fixes #59911
