Simon Charette c2d4926702 Fixed #31910 -- Fixed crash of GIS aggregations over subqueries.
Regression was introduced by fff5186 but was due a long standing issue.

AggregateQuery was abusing Query.subquery: bool by stashing its
compiled inner query's SQL for later use in its compiler which made
select_format checks for Query.subquery wrongly assume the provide
query was a subquery.

This patch prevents that from happening by using a dedicated
inner_query attribute which is compiled at a later time by
SQLAggregateCompiler.

Moving the inner query's compilation to SQLAggregateCompiler.compile
had the side effect of addressing a long standing issue with
aggregation subquery pushdown which prevented converters from being
run. This is now fixed as the aggregation_regress adjustments
demonstrate.

Refs #25367.

Thanks Eran Keydar for the report.

======
Django
======

Django is a high-level Python Web framework that encourages rapid development
and clean, pragmatic design. Thanks for checking it out.

All documentation is in the "``docs``" directory and online at
https://docs.djangoproject.com/en/stable/. If you're just getting started,
here's how we recommend you read the docs:

* First, read ``docs/intro/install.txt`` for instructions on installing Django.

* Next, work through the tutorials in order (``docs/intro/tutorial01.txt``,
  ``docs/intro/tutorial02.txt``, etc.).

* If you want to set up an actual deployment server, read
  ``docs/howto/deployment/index.txt`` for instructions.

* You'll probably want to read through the topical guides (in ``docs/topics``)
  next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific
  problems, and check out the reference (``docs/ref``) for gory details.

* See ``docs/README`` for instructions on building an HTML version of the docs.

Docs are updated rigorously. If you find any problems in the docs, or think
they should be clarified in any way, please take 30 seconds to fill out a
ticket here: https://code.djangoproject.com/newticket

To get more help:

* Join the ``#django`` channel on irc.freenode.net. Lots of helpful people hang
  out there. See https://freenode.net/kb/answer/chat if you're new to IRC.

* Join the django-users mailing list, or read the archives, at
  https://groups.google.com/group/django-users.

To contribute to Django:

* Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for
  information about getting involved.

To run Django's test suite:

* Follow the instructions in the "Unit tests" section of
  ``docs/internals/contributing/writing-code/unit-tests.txt``, published online at
  https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests
