  [mlir][transform] Plumb a simplified form of AffineMin folding into transform.pad-tiling-interface

This revision introduces a simple variant of AffineMin folding in makeComposedFoldedAffineApply
and makes use of it in transform.pad-tiling-interface.
Since this version explicitly call ValueBoundsInterface, it may be too expensive and is
only activate behind a flag.
It results in better foldings when mixing tiling and padding, including with dynamic shapes.

This should be further composed with #145068 to provide full simplification and address
the remaining TODO in the test.
