[PATCH 0/7] MR4565: winex11: Use helpers to attach / detach / destroy client windows.
After some discussion on https://gitlab.winehq.org/wine/wine/-/merge_requests/4533, this refactors how child_window are handled to make it easier to decouple them from the whole_window, and eventually have multiple detached child_window for some Vulkan use case (possibly also GL). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4565

I don't think it's very expensive compared to all the other operations that we have to do at this point (creating a window + XSync + XFlush + XMapWindow). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4565#note_54424
