workspace: Animate window clones using translation properties

Browse Source 
Instead of position x/y properties. This reduces CPU-intensive relayouts
in JavaScript (`vfunc_allocate` etc).

Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1271
since the other fix required already landed in 4c4846e9.
