Non-tuple exact and in lookups have specialized logic for subqueries that can
be adapted to properly assign select mask if unspecified and ensure the number
of involved members are matching on both side of the operator.

The original queryset._next_is_sticky() call never had the intended effect as
no further filtering was applied internally after the pk__in lookup making it
a noop.
In order to be coherent with how related filters are applied when retrieving
objects from a related manager the effects of what calling _next_is_sticky()
prior to applying annotations and filters to the queryset provided for
prefetching are emulated by allowing the reuse of all pre-existing JOINs.
Thanks David Glenck and Thiago Bellini Ribeiro for the detailed reports and
tests.

Just like normal queries, combined queries' outer references might fully
resolve before their reference is assigned its final alias.

Aggregation optimization didn't account for not referenced set-returning annotations on Postgres.

Previously the order was always extra_fields + model_fields + annotations with
respective local ordering inferred from the insertion order of *selected.
This commits introduces a new `Query.selected` propery that keeps tracks of the
global select order as specified by on values assignment. This is crucial
feature to allow the combination of queries mixing annotations and table
references.
It also allows the removal of the re-ordering shenanigans perform by
ValuesListIterable in order to re-map the tuples returned from the database
backend to the order specified by values_list() as they'll be in the right
order at query compilation time.
Refs #28553 as the initially reported issue that was only partially fixed
for annotations by d6b6e5d0fd4e6b6d0183b4cf6e4bd4f9afc7bf67.
Thanks Mariusz Felisiak and Sarah Boyce for review.
By always including related objects in the select mask via adjusting the
defer logic (_get_defer_select_mask()), it becomes possible for
select_related_descend() to treat forward and reverse relationships
indistinctively.
This work also simplifies and adds comments to
select_related_descend() to make it easier to understand.
While refs #34612 surfaced issues with reverse one-to-one fields
deferrals, it missed that switching to storing remote fields would break
self-referential relationships.
This change switches to storing related objects in the select mask
instead of remote fields to prevent collisions when dealing with
self-referential relationships that might have a different directional
mask.
Despite fixing #21204 introduced a crash under some self-referential
deferral conditions, it was simply not working even before that as it
aggregated the sets of deferred fields by model.
Thanks Joshua van Besouw for the report and Mariusz Felisiak for the
review.
Adjustments made to solve_lookup_type to defer the resolving of
references for summarized aggregates failed to account for similar
requirements for lookup values which can also reference annotations
through Aggregate.filter.

Special characters lose their special meaning inside sets of characters.
"-" lose its special meaning if it's placed as the first or last
character.

This also corrected test_inheritance_deferred2() test which was
previously properly defined and marked as an expected failure but was
then wrongly adjusted to mask the lack of support for per-alias
deferral that was fixed by #21204.
While deferring many-to-many and GFK has no effect, the previous
implementation of QuerySet.defer() ignore them instead of crashing.

The previous implementation resolved condition at Join compilation time
which required introducing a specialized expression resolving mode to
alter the join reuse logic solely during that phase.
FilteredRelation.condition is now resolved when the relation is first
referenced which maintains the existing behavior while allowing the
removal of the specialized resolving mode and address an issue where
conditions couldn't spawn new joins.
While the add_fields() call from set_values() does trigger validation it
does so after annotations are masked resulting in them being excluded
from the choices of valid options surfaced through a FieldError.
