Move surface size information out of SurfaceImpl. Some implementations need to query size information directly from their native window instead of listening for size events and storing the result. Also move mSwapInterval to SurfaceD3D since it doesn't need to be stored in all cases and there is no query for it. It no longer requires that the SurfaceImpl's derivation remembers to set mSwapInterval in setSwapInterval too.
