[Title] App selector will be launced when user select <input type=file> button
[Issue#] N_SE-52810, N_SE-53110
[Problme] Focus goes to image file instead of my files home page
[Cause] My files app launched gallery app with submode after that browser launched my files app and than my files app displayed gallery app previous launched
[Solution] Add service_set_window method for handling submode app and remove service_set_app_id so user can select app which user want
