REGRESSION(310189@main): SwipeProgressTracker::displayLinkFired() can assert
under WeakRef::get() on the CVDisplayLink thread
https://bugs.webkit.org/show_bug.cgi?id=314462
rdar://176624705
Reviewed by Richard Robinson.
SwipeProgressTracker::displayLinkFired may be called off the main
thread, but it dereferences a WeakRef<WebPageProxy> instance which has
main-thread assertions. Since we only access the WeakRef to obtain the
page identifier for dispatching to the main runloop, this patch stores
the identifier as a member at creation time and uses it directly in the
callback, matching precedent set by RemoteLayerTreeDisplayLinkClient.
