Subject: Add GL entry points for DiscardBackbufferCHROMIUM
This adds and uses a GL command buffer command for DiscardBackbufferCHROMIUM
instead of having a WebGraphicsContext3D entry point + common/ IPC message.
This is used to deallocate, if possible, the backbuffer when no longer in use.
BUG=181120
