Output layout

[Aki-7]

Description

Applications are able to know the layout of outputs, through xdg_output protocol.

Thanks to the wlroots, we can setup xdg output protocol only by notifying (x, y) of each output to wlr_output_layout.

However, as we have an immersive display system, to determine where to handle the position of output in 2d coordinate system is not that simple.

Fow now, all outputs are positioned in (0, 0)
