Revert "Fix regression caused by drawing accelerated content on SW canvas"

This reverts commit 67e499b1.

Reason for revert: As the revert crrev.com/c/2360557 is landed, revert this as well since they seem to tie with each other

Original change's description:
> Fix regression caused by drawing accelerated content on SW canvas
> 
> The recent change introducing PaintImage::GetSwSkImage() caused a
> regression that occurs when drawing accelerated resources on a software
> canvas.
> 
> This is a quick fix to revert the culprit caller back to
> PaintImage::GetSkImage(). This avoids the cost of multiple readbacks
> that GetSwSkImage() incurs. A follow up change will introduce caching in
> GetSwSkImage(), at which point we can use it again.
