exo: Improve frame callbacks.

Use the compositor frame ack instead of begin-frame callback to
trigger these callbacks. The frame ack is sufficient to prevent
frames from being dropped, and provides minimal latency
back-pressure for clients that implement more advanced
scheduling.

This makes it possible to improve scheduling of frames for
Linux apps significantly. Sommelier can have the next frame
prepared as a dmabuf and ready to commit when we receive the
callback. This minimizes the chance that we'll miss a frame.
