[Mlir-commits] [mlir] [MLIR][XeGPU] Add anchor_layout and update propagation to honor user-specified layouts (PR #169267)

It looks like anchor ops might benefit from a dedicated interface.

For us, it would make layout handling in ops easier (e.g., use it in `updateOp()` in propagation instead of within visitors).

For users, it would serve as a single place that clearly defines the "anchor" term and serves as an easy-to-notice marker for ops when reading tablegen.
