Torchinductor randn_like lowering (#93005)
Add lowering for randn_like, fixes https://github.com/pytorch/pytorch/issues/92368 by virtue of not taking a fallback path, although the 0-element prim stride is still incorrect. Would be nice to submit as a decomposition, but that is blocked by https://github.com/pytorch/pytorch/issues/92920.
