Support for multiple sync ModelSafeWorkers.
- Introduce an equivalence class enum to group sync model types that live on the same
chrome native model together.
- Remove ModelSafeWorkerBridge as it is no longer needed.
- Rename BookmarkModelWorker -> UIModelWorker, and make it use the new stuff.
- Allow syncable entries belonging to an "unsynced" model type to be just
processed "passively" from
the SyncerThread (rather than dispatching), and allow this to change as a result
of enable/disabling.
- Experimenting with a way to complete issue 31909 (the CLASS_UNASSOCIATED
stuff).
