This revision adds a new transformation to tile a TilingInterface `op` to a tiled `scf.foreach_thread`, applying tiling by `num_threads`. If non-empty, the `threadDimMapping` is added as an attribute to the resulting `scf.foreach_thread`. 0-tile sizes (i.e. tile by the full size of the data) are used to encode that a dimension is not tiled.
