  [RISCV] Use lowerScalarInsert in lowerReductionSeq [nfc]

Use the newly introduced helper routine.  At the moment, this generates the same code (at this call site!) since LMUL is restricted to LMUL1 or less, and VL is hard coded to 1.  In a future patch, I will loosen the second part.

  -----------
  [RISCV] Use lowerScalarInsert when folding op into reduction [nfc]

This doesn't cause any functional change since this is being applied to a insert generated by the same routine.  This is mostly about consolidating the logic for vmv.s.x into one place to simplify future changes.
