workspaceAnimation: Use window clones

Instead of reparenting windows, clone them. This will allow to properly
support multi-monitor setups in subsequent commits.

Block window mapping animation while the animation is running to prevent
new windows appearing during the animation from being visible at the same
time as their clones.
