Removed redundant QuerySet.all() calls in docs and tests. 
Most QuerySet methods are mapped onto the Manager and, in general,
it isn't necessary to call .all() on the manager.

Refs #33476 -- Refactored problematic code before reformatting by Black. 
In these cases Black produces unexpected results, e.g.

def make_random_password(
    self,
    length=10,
    allowed_chars='abcdefghjkmnpqrstuvwxyz' 'ABCDEFGHJKLMNPQRSTUVWXYZ' '23456789',
):

or

cursor.execute("""
SELECT ...
""",
    [table name],
)

Jamie Matthews f5233dce30 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.

Hasan Ramezani 3f7b327562 Fixed #31235 -- Made assertQuerysetEqual() compare querysets directly. 
This also replaces assertQuerysetEqual() to
assertSequenceEqual()/assertCountEqual() where appropriate.

Alex Aktsipetrov 681f7e2b13 Fixed #20577 -- Deferred filtering of prefetched related querysets.

Thanks Simon Charette for the review.

ElizabethU 54ea290e5b Fixed #30651 -- Made __eq__() methods return NotImplemented for not implemented comparisons. 
Changed __eq__ to return NotImplemented instead of False if compared to
an object of the same type, as is recommended by the Python data model
reference. Now these models can be compared to ANY (or other objects
with __eq__ overwritten) without returning False automatically.
