SkiaOutputSUrface checks the OutputDevice implementation for whether it
supports scheduling the primary plane as overlay. This is to match
GLOutputSurface's behavior, where only the BufferQueue implementation
would return true for IsDisplayedAsOverlay(). This also helps avoid
the case where a Surfaceless GLSurface is created for
SkiaOutputDeviceGL.
