Reconnect "full width" shade logic with scenes enabled

QS, ScrimController, and NSSL all have a boolean field for whether the
shade is using the entire width of the device. At this time, this
directly corresponds to whether the device is not fullscreen. When the
scene container is enabled, there is no NPVC to set these values, so
this change collects from a flow and set them.
