Fixed #18343 -- Cleaned up deferred model implementation
...
Generic cleanup and dead code removal in deferred model field loading
and model.__reduce__().
Also fixed an issue where if an inherited model with a parent field
chain parent_ptr_id -> id would be deferred loaded, then accessing
the id field caused caused a database query, even if the id field's
value is already loaded in the parent_ptr_id field.

Refs #17876 : enhanced new test to actually test underlying function, not just ensure trying to use it does not raise an exception. Thanks Przemek Lewandowski.

Fixed #5420 -- Added support for delayed loading of model fields.
...
In extreme cases, some fields are expensive to load from the database
(e.g. GIS fields requiring conversion, or large text fields). This
commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.
