Support impl-side painting in Mandoline.

This is now the default in cc and the old code paths are being removed, so we need to use impl-side painting. The changes are:
-add necessary thunks for the gl methods
-expose gpu::GpuMemoryBufferManager and cc::TaskGraphRunner in ui and html_viewer
-IPC to view_manager and call the GPU code (modelled on content)
