  [mlir][spirv] Update mergeInfo of blocks nested in regions (#137789)

The current code that updates mergeInfo iterates only over
constructBlocks, potentially leaving blocks nested in already structured
regions with invalid mergeInfo. This patch adds walk for each block to
ensure all nested blocks are considered.

It is not possible to add a unit test exercising this change as whether
the problem occurs depends on the structuring order that is currently
non-deterministic.
