Matthias Springer e4c14190bb [mlir][IR] DominanceInfo: Fix inconsistency in proper block/op dominance (#115413) ...

An operation is considered to properly dominate itself in a graph
region. That's because there is no concept of "dominance" in a graph
region. (`dominates` returns "true" for all pairs of ops in the same
block. It makes sense to do the same for `properlyDominates`.)

Previously, a block was *not* considered to dominate itself in a graph
region. This commit fixes this asymmetry between ops and blocks: both
are now properly dominating themselves in a graph region.
