We don't send the color space to the browser's ui::Compositor on macOS.
This has been broken on macOS for an unknown period of time. It didn't
actually make a difference because
- that only set the raster space for browser UI, which is sRGB anyway
- the renderer got the correct color space for raster via
  RenderWidgetHostImpl::GetScreenInfo
- we would draw using CoreAnimation (not GLRenderer) >99.9% of the
  time, so the ui::Compositor's GLRenderer's color space didn't matter
Because of rounded corner rects, we hit the GLRenderer more often,
causing this bug be visible.

Change RecyclableCompositorMac::UpdateSurface to take a required
color space argument, ensuring that all callers specify a value.
