[mutter/halfline/wip/kms-cleanups: 3/9] session-controller: make take_device method public

    session-controller: make take_device method public
    
    We ultimately want to move the renderering related code
    off to a separate file. When moved that code will need
    to call back to the session controller to do that actual
    talking to logind.
    
    This commit exports the take_device method from the
    session controller code, so that, in a later commit, the
    rendering code can make use of it.
