  [mlir][linalg] Allow pack consumer fusion if the tile size is greater than dimension size. (#149438)

This happens only when you use larger tile size, which is greater than
or equal to the dimension size. In this case, it is a full slice, so it
is fusible.

The IR can be generated during the TileAndFuse process. It is hard to
fix in such driver, so we enable the naive fusion for the case.
