  [MLIR] Bubble up tensor.extract_slice through tensor.collapse_shape (#131982)

Add a pattern that bubbles up tensor.extract_slice through
tensor.collapse_shape.
The pattern is registered in a pattern population function that is used
by the transform op
transform.apply_patterns.tensor.bubble_up_extract_slice and by the
tranform op transform.structured.fuse as a cleanup pattern.
This pattern enables tiling and fusing op chains which contain
tensor.collapse_shape if added as a cleanup pattern of tile and fuse
utility.
Without this pattern that would not be possible, as
tensor.collapse_shape does not implement the tiling interface. This is
an additional pattern to the one added in PR #126898
