Description

Some QuerySet methods rely on specialized querysets, namely: ValuesQuerySet(), and ValuesListQuerySet() (and previously DateQuerySet, and DateTimeQuerySet).

When we made custom QuerySet a public API these were a major pain point and required a clunky system with dynamically generated classes and pickle magic.

We already got rid of DateQuerySet and DateTimeQuerySet and now is time to remove the remaining two.

The iteration logic can be cleanly implemented through composition (ModelIterator, ValuesIterator, etc.) and the rest can be moved onto the main QuerySet class.
