  [RISCV] Recommit "Expand vp.stride.load to splat of a scalar load." (#98579)

This is a recommit of #98140. The old commit should be rebased on #98205
which changes the feature of hardware zero stride optimization.

It's a similar patch as a214c521f8763b36dd400b89017f74ad5ae4b6c7 for
vp.stride.load. Some targets prefer pattern (vmv.v.x (load)) instead of
vlse with zero stride.
