headless/cc/viz: Add animate_only BeginFrame param. See design doc here: http://bit.ly/bfc-animations. The headless::CompositorController runs intermediate BeginFrames while loading a page, for which we would like to avoid doing more work than necessary. This patch adds a new animate_only BeginFrame parameter. When this param is set, only select surfaces / BeginFrameObservers receive the BeginFrame. The compositor defers main frame commits for such BeginFrames and the main frame also skips the painting lifecycle phases, which are unnecessary since the commit will be aborted.
