I'll note that I am one of those downstreams who's relying on collapse/expand pairs for `tosa.reshape`, but I didn't raise it because I figured it'd be resolvable.

If there isn't already a pass that rewrites `tensor.reshape` to `tensor.collapse_shape` and `tensor.expand_shape` where possible, we might want to add one, since that could then be slid into the Tosa to Linalg pipeline to preserve the existing behavior.
