[mlir] Fix ComposeExpandOfCollapseOp for dynamic case (#142663)
Changes `findCollapsingReassociation` to return nullopt in all cases
where source shape has `>=2` dynamic dims. `expand(collapse)` can
reshape to in any valid output shape but a collapse can only collapse
contiguous dimensions. When there are `>=2` dynamic dimensions it is
impossible to determine if it can be simplified to a collapse or if it
is preforming a more advanced reassociation.
This problem was uncovered by
