ART: Pass driver generalization

- Generalizing Pass Driver.
- Migrating ME Pass Driver to use the new generalized Pass Driver.

There will be some more changes after in the compiler code to generalize
 it a bit more by separating what is being done by the optimizing passes
 and post-pass cleanups.
