aw: Page visiblity behind switch
Enable page visibility behind a command line switch. There should be
no change in behavior if enable-page-visibility switch is missing.
When it's added:
* Visibility is changed to
(view visible) && (!attached or window visible) && (!onPause-ed)
The existing implementation is simply !onPaused.
* Pass page visibility signal into blink, and in turn, the compositor.
