nsClipboard::HasDataMatchingFlavors() calls nsRetrievalContext::GetTargets() which obtains clipboard targets. We need to call Gtk code for that and spin evetn loop to get the targets. In this patch we store clipboard tragets internally to speed up nsClipboard::HasDataMatchingFlavors() calls. We also listen at owner-change signal to clear target cache when clipboard content changes. Differential Revision: https://phabricator.services.mozilla.com/D137899
