Use Seconds type for backForwardCacheExpirationInterval setting instead of
double, for clarity.

Handle back/forward cache entry expiration in the UIProcess instead of the WebProcess,
now that back/forward cache management is done in the UIProcess.

(WebKit::WebBackForwardCacheEntry::WebBackForwardCacheEntry):
(WebKit::WebBackForwardCacheEntry::takeSuspendedPage):
(WebKit::WebBackForwardCacheEntry::expirationTimerFired):
* UIProcess/WebBackForwardCacheEntry.h:
Add a Timer to WebBackForwardCacheEntry to make the entry expire after 30 minutes, which is what used
to happen on WebContent process side. One difference in behavior is that when the entry expires we
now remove it from the cache right away to free-up memory, instead of simply refusing to use it later
on.

* WebProcess/WebPage/WebPage.cpp:
Disable back forward cache expiration in the WebContent process when using modern
WebKit.
