docs(tvix/eval): update string context document

Browse source 
NixString doesn't contain a `HashSet<BuildReference>` anymore, there's a
more packed internal data structure. We don't need to be overly specific
in the docs, just say we expose an API.

In the past, Tvix did not track string contexts in its evaluator at all, see
the historical section for more information about that.
Tvix tracks string contexts in every `NixString` structure via a
`HashSet<BuildReference>` and offers an API to combine the references while
keeping the exact internal structure of that data private.
Tvix tracks string contexts in every `NixString` structure and offers an API to
do operations on the context (inherit/clear/…), as well as iterators over
(different types of) context elements, while keeping the exact internal
structure of that data private.
## Historical attempt: Persistent reference tracking
