  [RISCV][sema] Correct the requirement of `vf[n|w]cvt.x[|u].f` intrinsics (#101811)

Fix https://github.com/llvm/llvm-project/issues/101526

`vf[n|w]cvt.x[|u].f` for f16 needs `zvfh` instead of `zvfhmin`, current
approach
is not able to detect this. Ultimately we need to add `zvfh` to
RequiredFeatures
to check other intrinsics instead, the type check should be done in
checkRVVTypeSupport.
