Fix display list canvas fallback to GPU accelerated mode

Right now when the display list canvas fallback is triggered,
and the fallback canvas is GPU-acclerated, we fail to notify
the GraphicsContext that it has become
accelerated.  This causes HTMLCanvasElement::paint to use
the CPU rendering code path. This change fix the problem by
notifying the GraphicsContext of whether GPU acceleration
is use by the fallback canvas.
