  [mlir][CSE] Fix dominanceInfo analysis preservation (#192279)

The CSE pass calls `markAnalysesPreserved<DominanceInfo,
PostDominanceInfo>()` at the end. While CSE erases operations, it does
not remove their corresponding dominator trees, causing them to be
unnecessarily preserved in memory. This PR addresses the issue by
explicitly calling invalidate within CSE to clean up the dominator trees
for those erased operations.
