[RISCV] Change riscv_vid_vl isel pattern to use _MASK instruction.

The post isel peephole can convert it to the unmasked form.

We don't have any way to test the masked version right now because
we always use a true mask.

This makes the isel pattern consistent with many other instructions
that select the mask form.
