  [iOS] Entering PIP when watching trailer flashes smaller sized image/frame for a brief second

Reviewed by Eric Carlson.

When entering PiP, createLayerHostViewWithId() will be called by the WebContent process, though
the layer already exists and is parented in the PiP window. Setting the existing video view's
frame will cause it to unintentionally and visibly resize briefly. Only set the video view's
initial size when it is first created.
