Logging of "good" and "bad" disconnection.

Attaching some logging I did.
(1) "Good" is the case where the WebPage::Close message is properly received by the WebProcess, and everything shuts down cleanly. This is the typical case.

(2) "Bad" is the case where the IPC connection between UIProcess and WebProcess is severed before WebPage::Close is received by the WebProcess.
