ENH: relocate labelPairLookup into OpenFOAM library (as labelPairHashes.H)

- simplifies organization, allows reuse.
  provide some other useful hash types.

-Typedef
-    Foam::labelPairLookup
-
-Description
-    A HashTable for two labels to another label.
-    Used for e.g. for face1, face2 to shared edge.
-
-Note
-    The hash table is based on a FixedList and not edge, since an edge
-    hashes commutatively!
