Fixed #33397 -- Corrected resolving output_field for DateField/DateTimeField/TimeField/DurationFields.
...
This includes refactoring of CombinedExpression._resolve_output_field()
so it no longer uses the behavior inherited from Expression of guessing
same output type if argument types match, and instead we explicitly
define the output type of all supported operations.
This also makes nonsensical operations involving dates
(e.g. date + date) raise a FieldError, and adds support for
automatically inferring output_field for cases such as:
* date - date
* date + duration
* date - duration
* time + duration
* time - time

The lack of _for_write = True assignment in bulk_update prior to

wrap batched UPDATEs in a transaction.
Also tweaked the batch queryset creation to also ensure they are
executed against the same database as the opened transaction under all
circumstances.

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.
