[gnome-boxes] Turn LibvirtMachine.state from property to a method

    Turn LibvirtMachine.state from property to a method
    
    This was getting called in multiple places as if it was a cheap method, while
    in reality its a blocking rpc call. Sometimes it was even used multiple times
    within a method.
    
    The new method is called get_state_sync() to make it obvious that this is a
    blocking call.
