33bb8249 - [MLIR][XeGPU] Rematerialize layout conversion sources after conflict resolution (#230669)

[MLIR][XeGPU] Rematerialize layout conversion sources after conflict resolution (#230669) This PR separates layout conflict resolution from rematerialization. The resolver now inserts xegpu.convert_layout for conflicts ....a following step clones eligible, cheap vector producer chains in the target layout and replaces those conversions. This avoids SLM round trips.
