[Codegen] Do not swap extract_slice and collapse_shape for a special case (#22870)

This is a stop gap fix for
https://github.com/iree-org/iree/issues/22833.

In this special case, the `collapse_shape` is from `unpack` op
decomposition and there is no benefit to swap it with `extract_slice`.
`collapse_shape` is then used as a blocker to avoid fusing
`extract_slice` into `scf.forall`. Otherwise, an extra private
allocation may be created. Some attempts were made to remove the extra
`tensor.empty`, however, some other tests would fail as shown in
https://github.com/iree-org/iree/pull/22861.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.
