Replace resize_axis with wlr_edges

Browse Source 
This patch removes the resize_axis enum in favour of wlr_edges. As
wlr_edges has no `horizontal` or `vertical` value, it denotes these by
bitwise `or`ing the left/right and up/down values. Two constants are
defined to make it easier to refer to these.

This will allow the tiling resize seatop to utilise the functions in
this file. resize_axis was local to the resize command and couldn't be
exposed in function arguments.
