Remove a batch of deprecated optimizers (quantumlib#5727)

These optimizers have all been migrated to transformers: Removes: DropEmptyMoments, DropNegligible, EjectPhasedPauli, EjectZ, ExpandComposite, MergeInteractions, MergeInteractionsAbc, MergeInteractionsToSqrtIswap, and SynchronizeTerminalMeasurements.
