[Global Opt] Fix transpose propagation failure (iree-org#19322)

When applying the "bubbling" patterns in the transpose propagation pass,
the greedy rewriter was failing because it reached 10 iterations before
converging. This PR sets the iteration limit to `kNoLimit` which is the
same config used for the "sinking" patterns that are applied afterwards.
This is needed because these patterns take a bit to converge.

Fixes iree-org#19320
