Marshall Greenblatt 8c6cc302d0 Fix OSR surface sizing on browser resize (fixes issue #2733).
This includes the following changes:
- Update usage of surface IDs to match the Aura implementation from the
  RWHVAura/Window classes.
- Batch CefBrowserHost::WasResized calls to avoid excessive/unnecessary calls
  to SynchronizeVisualProperties.
- Cache the results of CefRenderHandler::GetViewRect after resize and make
  RWHVOSR::GetViewBounds the source of truth for all size calculations.
- Fix bounds calculations in CefVideoConsumerOSR with GPU enabled.

Known issues:
- The size passed to OnPaint may be off by 1 pixel in cases where the device
  scale factor is not 1 and does not divide evenly into the pixel size. This is
  due to the inexact conversion from integer pixel size to integer logical size
  for GetViewRect.
