    [NTOS:SE] Declare function prototypes & add OBJECT_TYPE_LIST_INTERNAL
    
    OBJECT_TYPE_LIST_INTERNAL will serve as an internal kernel data structure
    to hold validated object type contents that are copied from UM.
    
    The difference between the public and the internal one is that the internal structure
has
    an additional member for access check rights that have been granted on each
    object element in the list.
