Crash under DisplayRefreshMonitorManager::displayWasUpdated()
https://bugs.webkit.org/show_bug.cgi?id=199808
<rdar://problem/53070144>

Reviewed by Geoffrey Garen.

Copy m_monitors before iterating over it because the calling displayLinkFired() on the
monitor may end up calling DisplayRefreshMonitorManager::displayDidRefresh() synchronously,
which removes the monitor from m_monitors.
