[Flow] Dump affinity info in DumpDispatchGraph pass. (iree-org#20888)

No tests are added because they don't exist. It dumps more information,
so we can do basic affinity analysis outside the main tree. E.g., people
can use the tool from https://github.com/hanhanW/iree-toolbox to verify
if the input program has reasonable affinity assignment or not.
