TODO(Leo): add name_generator to type_context, tactic_state, and this class.
When we create a `tactic_state_context_cache`:
1- Let `N` be the `name_generator` at `s`, then use it to create a child `name_generator` for this object.
2- Update `tactic_state & s` with new `N`.
3- Use the `name_generator` stored here to provide a child `name_generator`
to each `type_context` created using `mk_type_context`.
In this way, we don't have to propagate the name_generators back only forth.
However, we will have to make sure we have replaced every occurrence of mk_type_context_for
with this helper class. */
