  [MLIR][Affine] Simplify affine.for bounds by pruning redundant expressions via ValueBoundsConstraintSet (#199032)

This PR introduces a new pattern `SimplifyAffineForBoundMap` to simplify
multi-result lower and upper bounds of `affine.for` loops by pruning
redundant expressions leveraging `ValueBoundsConstraintSet`. This PR
addresses the limitation where the built-in folder of `affine.for` can
only handle constant bounds.
