Implement orientation (placement of master area) for master layout (#1202)

* Implemented choosing placement of master area (#1059)

This implement a per workspace 'orientation' that can be set
to left, right, top or bottom. Reflecting placement of the master area.

Left (default) and right are horizontal layouts, top and bottom produce vertical
layouts. Orientation can be switched with: 'hyprctl dispatch layoutmsg orientationleft'
