SkiaRenderer/macOS: Use IOSurfaceInUse to not recycle in-use resources

Add a method GLImage::IsInUseByWindowServer. This is implemented
only macOS, and queries the IOSurfaceIsInUse method. Roll the
the function GLImageIOSurface::CanCheckIOSurfaceIsInUse into the
GLImageIOSurface::IsInUseByWindowServer function.

Add two accessors to viz::OutputPresenter::OverlayData. One is
IsInUseByWindowServer (which calls the method on the GLImage).
The second returns the mailbox for the the overlay.

Add viz::SkiaOutputDeviceBufferQueue::in_use_by_window_server_overlays_,
which is a map from gpu::Mailbox to viz::OutputPresenter::OverlayData.
When overlays are swapped in SkiaOutputDeviceBufferQueue::
DoFinishSwapBuffers, move them into this map, and remove any entries
that are no longer in use.
