cc: Add tile-free software compositing mode.
In Android WebView, CC will be run in a hybrid hardware/software mode
where the renderer used may vary frame by frame. We're planning to
reserve the ResourceProvider exclusively for GL tiles; for the software
case, we'll draw directly from the PicturePile instead.
This patch implements this draw-direct-from-PicturePile flow by adding
PictureDrawQuad support to SoftwareRenderer and introducing a
OutputSurface-based setting telling PictureLayerImpl to only append
PictureDrawQuads for the current frame.
