workspaceAnimation: Use separate WorkspaceBackground class
Separating WorkspaceGroup and WorkspaceBackground allows each to
track its own set of windows without special-casing exceptions.
This will also give us more flexibility in the future, if we need
to reuse the background elsewhere. This may happen if we optionally
change the animation to a crossfade for the new `reduced-motion`
setting.
