  [mlir][vector] Refine vector.transfer_read hoisting/forwarding (#65770)

Make sure that when analysing a `vector.transfer_read` that's a
candidate for either hoisting or store-to-load forwarding,
`memref.collapse_shape` Ops are correctly included in the alias
analysis. This is done by either
* making sure that relevant users are taken into account, or
* source Ops are correctly identified.
