Implement borders

The borders are implemented as a surface/buffer attached to each view
which is sent to and rendered by wlc in the view_pre_render callback.

All the drawing logic is handled in sway/border.c and all the logic for
calculating the geometry of the border/view is handled in
`update_geometry` in sway/layout.c (same place as gaps are calculated).
