HHH-19010 get rid of inheritance of SessionFactoryImplementor from query creation context stuff

Let's make the NodeBuilder the thing that is the SqmCreationContext, and introduce a
new thing that performs a similar role for SqlAstCreationContext. The reason here is
twofold:

- it is part of my long struggle to decouple query parsing/typing from the
  SessionFactory, in order to make HibernateProcessor less of a hack and I
  guess more robust
- SessionFactoryImplementor was already starting to be polluted with weird
  little operations that didn't belong there. That will only get worse with
  time.
