[FLOW] Move InitializeEmptyTensors before CaptureDynamicDims #19563

Some patterns take in a tensor.empty op as the iter_arg for scf.for ops, but these ops don't get handled when capturing dynamic dims. Moving the conversion of tensor.empty to flow.tensor.empty before CaptureDynamicDims allows these dynamic dims to properly propagate through the loop.

If someone could help me figure out what kind of test would be appropriate for this, I would appreciate it.

Could you add a small test for this?

It looks like were missing tests for --iree-flow-transformation-pipeline. @zjgarvey maybe you could create something similar to https://github.com/iree-org/iree/blob/main/compiler/src/iree/compiler/DispatchCreation/test/pipeline_tests.mlir but for flow?
