[VizLayers] Push basic display tree updates

Pushes basic tree metadata as well as the transform property tree.
Subsequent CLs will add layers and other property trees.

This also corrects a few minor issues in display tree lifecycle:

- Pushing the tree from the client will update its "needs first draw"
  bit in the scheduler so we don't trigger an endless stream of
  redundant BeginFrames after one activation.

- Don't push a frame ack back to the client for frames submitted
  by LayerContextImpl.

- Display tree teardown no longer tries to clean up state related
  to tiles or UI resources, which display trees don't manage.
