This CL:
1. Makes the former |max_width|, |max_height| parameters in
VideoTrackAdapterSettings a single optional gfx::Size |target_size|.

2. Changes VideoTrackAdapter so that if no |target_size| is specified
in VideoTrackAdapterSettings, no rescaling will occur.

3. Changes VideoTrackAdapterSettings to a class to increase encapsulation.

4. CalculateTargetSize() is renamed to CalculateDesiredSize() and it now
returns a bool indicating if it was possible to compute a desired size.
If not, it means the input frame should not be rendered.
Currently this is limited to frames of invalid size (greater than the system
limit), but it will be expanded in follow-up work to detect frames that
violate constraints and should cause the overconstrained event to be fired.

These changes are in anticipation of support for the resizeMode constrainable
property and the overconstrained event.
