Summary REGRESSION(285922@main): Crash in `WebPageProxy::sendPreventableTouchEvent`

Some UI -> WCP messages use a completion handler when an event has been handled, instead of explicitly sending DidReceiveEvent. If a completion handler returns because a WCP has terminated, we won’t have an IPC::Connection& to use for the message checks in didReceiveEvent, leading to a release assertion failure when attempting to access the connection for the mainframe process. We should revert these changes until we have a better way to get an IPC::Connection using sendWithAsyncReply with site isolated web processes.
