 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.
