MdePkg/BaseLib: Add IsNodeInList() function.

Browse Source 
This patch adds IsNodeInList() to BaseLib, which verifies the given
Node is part of the doubly-linked List provided.

V2:
  - Rename "List" to "FirstEntry" and "Node" to "SecondEntry" to clarify that
    "FirstEntry" does not need to be the doubly-linked list's head node.

V3:
  - Remove ASSERTs from IsNodeInList() which are present in
    InternalBaseLibIsListValid().
