Split TuplesortPublic from Tuplesortstate 

The new TuplesortPublic data structure contains the definition of
sort-variant-specific interface methods and the part of Tuple sort operation
state required by their implementations.  This will let define Tuple sort
variants without knowledge of Tuplesortstate, that is without knowledge
of generic sort implementation guts.
