Implement Wayland support using PipeWire and xdg-desktop-portal
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.
