Add taskbar icons unfold animation

Adds 'move from center' animation for taskbar icons when
unfolding foldable devices.

Moves unfold transition progress provider from quickstep
launcher activity to TouchInteractionService to widen
the scope when this provider is available to cover
both launcher activity and taskbar.

Launcher activity and taskbar get their own instances
of unfold transition progress provider using
ScopedUnfoldTransitionProgressProvider wrapper.
This wrapper allows to get transition progress provider
that emits events only when clients are ready to handle them.
