<h3>Log Message</h3>
<pre>Port Page timer throttling to use ActivityState instead of PageThrottler
https://bugs.webkit.org/show_bug.cgi?id=164291
Reviewed by Geoff Garen & Antti Koivisto.
ActivityState now conveys this information; after this change PageThrottler is redundant and can be removed.
* page/Page.cpp:
(WebCore::Page::updateTimerThrottlingState):
- determine page throttling mode based on IsAudible/IsLoading in ActivityState.
(WebCore::Page::setActivityState):
- call updateTimerThrottlingState if IsAudible/IsLoading change.
* page/Page.h:
(WebCore::Page::pageActivityStateChanged):
- no need to listen for PageActivityState changes from the PageThrottler.</pre>
