Add a flag to tint GL-composite contents.
In order to debug HW overlay, we need to distinguish between
quads that are directly scanned out and quads that are composited
using GL.
This CL adds a flag to tint all the GL-composited contents to red.
In this way when we can notice when we promote an quad to HW
overlay (it won't be tinted).
Originally we added a similar feature, drawing border on GL composited
quads. That debugging feature caused confusion. The hope is that
this new way of debuggining HW overlays is going to be more intuitive.
Test: tested manually enabling the flag in about://flags.
