  -----------
  [RISCV] Fold vfmv.f.s of f16 into load from stack (#110214)

After #110144, we can finish off #110129 and fold f16 vfmv.f.s into a
flh.
vfmv.f.s is only available for f16 with zvfh, which in turn requires
zfhmin so we can use flh.

bf16 has no vfmv.f.s so the extract_vector_elt is lowered as an integer
in #110144, and gets the existing integer vmv.x.s fold.
