[NO ISSUE][FUN] Introduce IEvaluatorContext

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Introduce IEvaluatorContext - a context for evaluators
  that is available both at runtime and during constant
  folding at compile time
- IEvaluatorContext provides access to IHyracksTaskContext
  which is only available at runtime. At compile time this
  accessor returns null
- Instantiate evaluators with IEvaluatorContext
  instead of IHyracksTaskContext
