backend/x11: Implement a few useful window properties

Browse source 
It is currently impossible to tell if an X11 window is created by
wlroots, or what process / client it belongs to.

The following properties are now added to the window:
* WM_CLASS
* WM_CLIENT_MACHINE
*  _NET_WM_PID

Sample xprop output:
WM_CLASS(STRING) = "X11-1", "wlroots"
WM_CLIENT_MACHINE(STRING) = "My-Desktop"
_NET_WM_PID(CARDINAL) = 3629306
