In order for Expression.relabeled_clone to work appropriately its
get_source_expressions method must return all resolvable which wasn't the case
for Lookup when its right-hand-side is "direct" (not a compilable).
While refs #22288 added support for non-literals iterable right-hand-side
lookups it predated the subclassing of Lookup(Expression) refs #27021 which
could have been an opportunity to ensure right-hand-sides are always resolvable
(ValueList and ExpressionList).
Addressing all edge case with non-resolvable right-hand-sides would require
a significant refactor and deprecation of some parts of the Lookup interface so
this patch only focuses on FieldGetDbPrepValueIterableMixin (In and Range
lookups) by making sure that a right-hand-side containing resolvables are dealt
with appropriately during the resolving phase.
Thanks Aashay Amballi for the report.
