b6e4d27c - [MLIR][Mem2Reg] Extract shared utilities for PromotableRegionOpInterface (#188514)

[MLIR][Mem2Reg] Extract shared utilities for PromotableRegionOpInterface (#188514) The `PromotableRegionOpInterface` implementations use two helpers that are likely useful for other dialects implementing this interface as well: - `updateTerminator`: Appends the reaching definition as an operand to a block's terminator, falling back to a default when the block has no entry (e.g. dead code). - `replaceWithNewResults`: Clones an operation with additional result types while preserving its regions, then replaces the original. This PR extracts them into a common utility header so that downstream dialects can reuse them directly. I'm open to discussion about the location of these utilities.
