[mlir][linalg] Fix tensor tiling together with interchange

[mlir][linalg] Fix tensor tiling together with interchange

In `linalg::tileConsumerAndFuseProducers`, there are two levels of
tiling and fusion; we partition the tile sizes and only use one
half for each of them. The partition is using the first non-parallel
dimension *after* interchange as the boundary. However, concrete
tiling happens *together with* loop interchange, so we still need
to provide the partial tile sizes *before* the interchange.
Otherwise, there will be inconsistency, which is what this patch
is to fix.
