[NFC][DecoderEmitter] Predicate generation code cleanup (#158140)
Eliminate `doesOpcodeNeedPredicate` and instead have
`emitPredicateMatch` return true if any predicates were generated.
Delegate actual predicate generation in `emitPredicateMatch` to
`SubtargetFeatureInfo::emitMCPredicateCheck`. Additionally, remove the
redundant parenthesis around the predicate conditions in the generated
`checkDecoderPredicate` function.
Note that for ARM/AMDGPU this reduces the total # of predicates
generated by a few. It seems the old code would sometimes generate
duplicate predicates which were identical in semantics but one had an
extra pair of parentheses (i..e, `X` and `(X)`). `emitMCPredicateCheck`
does not seems to have that issue.
