Allow X11 clients to create shared pixmaps via the MIT-SHM extension under Xwayland. Tested with a wlroots patch [1]. Also add a few assertions to make sure we have wl_buffers where we need them.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
