Follow up to #4213. Fixes #4083. (Also contains a one-line change to fix #4225.)

I'm open to name suggestions for MergeInteractionsToSqrtIswap.

This is unblocked now @tanujkhattar. I changed the API to match the updates in #4213.

What's the idea behind testing the behavior caused by other follow-up optimizations here? I think this has the risk of making the unit tests brittle. Maybe we should have a separate place for such integration tests where we actually prescribe this sequence of optimizations and then test their combined behavior?

I copied most of the tests from merge_interactions_test.py. I think the test is trying to be less brittle to changes in the two-qubit synthesis method by relying on more basic optimizers.
