Deleted code associated with --enable-gpu-rendering and

--enable-video-layering flags. With the introduction of accelerated
compositing to Chromium this code is now obsolete, and it is causing
problems and bug reports when users experiment with these flags.

Tested on Linux in the following configurations:
 - Compositor on, CSS 3D content
 - Compositor on, HTML5 video content
 - Compositor off, HTML5 video content

Also ran patch successfully through the try bots.

BUG=54932
TEST=none
