[5.2.x] Fixed #35677 -- Avoided non-sticky filtering of prefetched many-to-many.

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.

Backport of 2598b371a93e21d84b7a2a99b2329535c8c0c138 from main.
