[FMV][AArch64] Expand feature dependencies using AArch64::ExtensionSet. (#113281)
Currently we maintain a hand written list of subtarget features which we
are implied for a given FMV feature. It is more robust to expand such
dependencies using ExtensionDependency from TargetParser, since that is
generated by tablegen. For this to work each FMV feature must have a
corresponding SubtargetFeature in place. FMV features which didn't
satisfy this criteria have been removed from the ACLE specification
(https://github.com/ARM-software/acle/pull/315). However, I deliberately
marked the ArchExtKind in FMVInfo structure as std::optional in case we
decide to break this rule in the future.
I have also added the missing dependencies:
* FEAT_DPB2 -> FEAT_DPB
* FEAT_FlagM2 -> FEAT_FlagM
