Add requestedVisibleTypes to TaskInfo

To allow Shell to know the inset types requested by each window/task
instead of the global aggregate available through InsetsState. This will
enable showing additional maximize/immersive UI affordances in the
caption bar depending on whether a specific window is requesting
immersive mode or not.
