Calling OpenGL from the renderer process

- Added ability for renderer processes to render to a real window (Windows only so far).
- Added ability to create offscreen frame buffer objects that can be resized later.
- OpenGL context can have a "parent" context that can access its last swapped back buffer through a texture ID.
- Moved code to establish GPU channel from RenderWidget to RenderThread.
- Changed way service size command buffer object lifetimes are managed.
TEST=trybot and visual verification that OpenGL can clear the browser window to magenta.
BUG=none
