MdePkg/BaseLib: Update internal LinkedList verifications.

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().
