Rare crash in RemoteScrollingCoordinator::~RemoteScrollingCoordinator
https://bugs.webkit.org/show_bug.cgi?id=290064
rdar://147211165
Reviewed by Chris Dumez.
Crash data suggest that m_webPage can be null in
RemoteScrollingCoordinator::~RemoteScrollingCoordinator().
Fix by caching the PageIdentifier, so that we can reliably call
WebProcess::singleton().removeMessageReceiver().
Also drive-by null-check m_webPage in
RemoteScrollingCoordinator::scheduleTreeStateCommit().
