WId is irrelevant on Wayland and it doesn't fully describe everything we
might be doing, we can pass a variant map to make sure all necessary
information is provided.
Summary:
Adds a new framebuffer implementation, which uses xdg-desktop-portal to support remote
desktop on Wayland and uses PipeWire to deliver the screen content. So far only mouse
support is implemented, because keyboard support is missing on KWin side.
