We do not add background animation when opening target is translucent
Added additional check to not animate background if launcher is not
closing (which is already a subset of all-targets-translucent)
Also removing reverse background animation from widgets, similar
to app-icons as it is never added for launcherNotClosing path

Test: Added translucent activtiy and widget and verified manually
that the behavior does not change
