calc66: #i103331# make OFFSET with external references work again

+ Introduced FormulaSubroutineToken to hold a FormulaTokenArray.
* INDIRECT in case of external reference returns FormulaSubroutineToken
  instead of directly pushing the token array to code and signalling its
  presence to ScInterpreter::Interpret().
* ScInterpreter::ScExternalRef() checks if an external reference is used with
  OFFSET and if so does not resolve it but pushes it so it can be handled
  within OFFSET.
+ OFFSET recognizes external reference and creates an external reference of
  the new area and returns that as subroutine to be resolved by
  ScExternalRef().
* Interpret() pushes the subroutine to code and rememberes the token and array
  for late destruction.
