Add a ChromeClient API that gets called whenever the Page's audio playing state has changed

[Ada Chan]

It'll most likely be:

virtual void isPlayingAudioDidChange(bool)

to match the

bool isPlayingAudio() const;

we are adding to WebCore::Page.  See https://bugs.webkit.org/show_bug.cgi?id=137218.

Nit: You don't need to include the (commented out) parameter name here. It's obvious from the function name.

I'll remove it.  Thanks for the review!
