[GTK][WPE] Poor scrolling performance after a history navigation with PSON
enabled
https://bugs.webkit.org/show_bug.cgi?id=252044
Reviewed by Žan Doberšek.
With PSON, when there's a history navigation the WebPage replaces the
drawing area with a new one. In case of coordinated graphics, the new
drawing area ends up using the wrong display refresh monitor because
DrawingArea::createDisplayRefreshMonitor() is not called. We call
WebPage::windowScreenDidChange() after creating the LayerTreeHost to
ensure DrawingArea::createDisplayRefreshMonitor() is called, but in this
case the page is the same, and the displayID hasn't really changed. So,
we need to ensure that the displayID we create is not based on WebPage
unique identifier, but on DrawingArea's because the
ThreadedDisplayRefreshMonitor needs to be created for every DrawingArea,
not WebPage.
