ShellTranstion: Apply recents input consumer when the window in transion

Like legacy recents animation will check if the focused window is
animating with recents animation, if so, requests the input focus on
recents input consumer, if not, means the window is not controlled by
recents animation and we should give it focus.
(e.g. Tapping on StatusBar)

Otherwise the input focus will be consumed by recents input consumer
and then tapping the editor on direct-reply notification will not able
to show IME.
