Bug 1717476 [Wayland] Change nsWaylandDragContext to RefPtr<DataOffer> in nsWindow code, r=jhorak Depends on D118577 Differential Revision: https://phabricator.services.mozilla.com/D118578

Bug 1717476 [Wayland] Imlement async clipboard data get, r=jhorak Firefox uses synchronized clipboard data get/set which causes issues when clipboard data is transferred in scope of Firefox itself as getting code blocks the sending one. As a workaround X11 clipboard code runs restricted message loop (processes clipboard events only), Wayland clipboard handler uses fast (direct) path when clipboard data is owned by Firefox and D&D code runs main loop for some limited time. When D&D operation is used on Wayland we can't determine clipboard data owner - so we can't use the fast (direct) data transfer but we always read data from wayland clipboard. That approach block when D&D data comes from Firefox itself. In orded to fix that this patch does: - Implement DataOffer::GetDataInternal() as non-blocking, i.e. fail when we can't get data from file descriptor provided by Wayland clipboard code. - Create new thread and run DataOffer::GetDataInternal() there - Run limited main event loop as D&D code does. In order to make the changes possible we also need to better track wayland data offers: - Implement DataOffer as ref counted general wayland clipboard data placeholder - Implement WaylandDragAndDropDataOffer for D&D data events - Track all offers in offer cache (mActiveOffers) Differential Revision: https://phabricator.services.mozilla.com/D118577
