This PR introduces the amdaie.flow operation (in consistency with aie.flow). This operation represents connections between ports/channels on tiles in the array and is lowered to aie.flow for routing. This idea is to lower amdaie.connection to amdaie.flow + DMA operations, however this PR goes halfway by creating amdaie.flow operations, while still keeping a reference inside amdaie.connection as the latter is still needed inside LowerToAIE for lowering to the AIE dialect DMA operations. This will be cleaned up in the future, but for now, this enables me to start adding routes for control packets in conjunction with data routes for https://github.com/nod-ai/iree-amd-aie/issues/714.
