SurfaceFlinger: use duration instead of offset
This change is using the duration given to sf/app without
converting them back to the legacy offset. This allows us to get
the expected vsync associated with a wakeup event.
This change also required some refactoring:
- Move the periodic callback interface out of DispSync and in
to DispSyncSource
- Translate legacy offsets to duration in case that duration
is not specified in the build files
- Add support to VSD to expose the deadline timestamp of when
a frame needs to be ready by
