Fixed #32511 -- Corrected handling prefetched nested reverse relationships.
...
When prefetching a set of child objects related to a set of parent
objects, we usually want to populate the relationship back from the
child to the parent to avoid a query when accessing that relationship
attribute. However, there's an edge case where the child queryset
itself specifies a prefetch back to the parent. In that case, we want
to use the prefetched relationship rather than populating the reverse
relationship from the parent.

Fixed #33406 -- Avoided creation of MaxLengthValidator(None) when resolving Value.output_field for strings.
...
This brings the behaviour in line with Field subclasses which append to
the validators within __init__(), like BinaryField, and prevents the
creation of a validator which incorrectly throws a TypeError, if it
were used.

Field.db_check() should return None or a SQL string.
Returning [] happened to work because it’s falsey.

Fixed #33282 -- Fixed a crash when OR'ing subquery and aggregation lookups.
...
As a QuerySet resolves to Query the outer column references grouping logic
should be defined on the latter and proxied from Subquery for the cases where
get_group_by_cols is called on unresolved expressions.
Thanks Antonio Terceiro for the report and initial patch.

Refs #32690 -- Altered lookups Query rhs alterations during initialization.
...
Having it happen at the lookup creation time ensures entry points
called before the compilation phase (e.g. get_group_by_cols) don't have
to duplicate the logic in charge of altering Query instances used as
rhs.
It also has the nice effect of reducing the amount of time the
alteration logic to once as opposed to multiple times if the queryset
is compiled more than once.
