  [mlir][vector] Distribute all non-permutation or broadcasted masked transfer reads (#73539)

The primary difficulty with distribution of masked transfers is when the
permutation map permutes the vector, in which case the distribution
logic needs to make sure the correct mask elements end up with the
distributed transfer. This is only tricky when the permutation map has a
permutation in it, so we can relax the condition for distribution.
