    sessionMode: Add 'allowScreencast' property
    
    Our built-in screen recorder is implemented as a component, so it will
    just be disabled when the session mode doesn't allow screencasting.
    However we will expose screencasting functionality on DBus as well, and
    while it makes sense to restrict its availablity to the same modes as
    the existing recorder, exporting/unexporting the service depending on
    the session mode is not very consumer friendly.
    For that reason, add an additional 'allowScreencast' property that for now
    mirrors the availability of the 'recorder' component.
