MdePkg/BaseLib: Update internal LinkedList verifications.
    
    1) Replace InternalBaseLibIsNodeInList() with
       InternalBaseLibIsListValid().
       - The verification whether Node is within the doubly-linked List
         is now done by IsNodeInList().
       - Whether the list is valid is returned.
    
    2) The comments within InsertHeadList() and InsertTailList() stated
       that it is checked whether Entry is not part of the doubly-linked
       list. This was not done as argument 3 of
       InternalBaseLibIsNodeInList() indicated whether the check is done,
       not whether to check if the node is or is not in the list. This
       has been fixed by using IsNodeInList() for the ASSERTs.
    
    V2:
      - Fix IsListEmpty() to ASSERT when the passed list is invalid.
      - Introduce the VERIFY_IS_NODE_IN_LIST() macro to only verify whether the
        passed node is part of the list when PcdVerifyNodeInList is TRUE.
    
    V3:
      - Introduce the ASSERT_VERIFY_NODE_IN_VALID_LIST() macro which,
        depending on the value of PcdVerifyNodeInList, verifies whether
        SecondEntry is or is not part of the same doubly-linked list as
        FirstEntry and unconditionally verifies whether the doubly-linked
        list FirstEntry is part of is valid. This prevents
        InternalBaseLibIsListValid() from being called twice when a
        function ASSERTs via the result of IsNodeInList(), as it calls
        InternalBaseLibIsListValid() already.
      - Remove the VERIFY_IS_NODE_IN_LIST() macro in favor of
        ASSERT_VERIFY_NODE_IN_VALID_LIST().
