  -----------
  [mlir][linalg] Improve linalg.pack consumer fusion. (#148993)

If a dimension is not tiled, it is always valid to fuse the pack op,
even if it has padding semantics. Because it always generates a full
slice along the dimension.

If a dimension is tiled and it does not need extra padding, the fusion
is valid.

The revision also formats corresponding tests for consistency.
