[RISCV] Match single source deinterleave shuffles for vnsrl (#114878)
We had previously only been matching the two source case where both
sources came from a wider source type. We can also match the single
source case - provided the result is m4 or smaller because we will need
a wider type to represent the source.
The main goal of this to ensure that vnsrl matching is robust to a
possible change in canonicalization for length changing shuffles that
I'm considering, but it has the nice effect of picking up a few cases we
missed along the way.
