It contains lot of refactor along with the pass logic itself.
Once you're done, it might be useful to split this into two PR.

What if there are more than 2 target core ops per DMA?
Able to get combined op - need to change the corresponding L2 target.

This PR adds a new pass
iree-amdaie-combine-logical-objectfifos-for-connection-reuse(can rename) which is the follow-up pass foriree-amdaie-split-logical-objectfifos-for-connection-reuse.It contains lot of refactor along with the pass logic itself. Since it's a non-trivial pass, I've tried adding asserts/checks (to the extend I could) - currently starting off with base lit test.
Aims to address point 4 in #644.
