Fixed #35744 -- Relabelled external aliases of combined queries.

Just like normal queries, combined queries' outer references might fully
resolve before their reference is assigned its final alias.

for the review.

Fixed #35559 -- Avoided unnecessary query on sliced union of empty queries.
...
While refs #34125 focused on the SQL correctness of slicing of union of
potentially empty queries it missed an optimization opportunity to avoid
performing a query at all when all queries are empty.
Thanks Lucidiot for the report.

Refs #28900 -- Made SELECT respect the order specified by values(*selected).
...
Previously the order was always extra_fields + model_fields + annotations with
respective local ordering inferred from the insertion order of *selected.
This commits introduces a new `Query.selected` propery that keeps tracks of the
global select order as specified by on values assignment. This is crucial
feature to allow the combination of queries mixing annotations and table
references.
It also allows the removal of the re-ordering shenanigans perform by
ValuesListIterable in order to re-map the tuples returned from the database
backend to the order specified by values_list() as they'll be in the right
order at query compilation time.

for annotations by d6b6e5d0fd

Fixed #33768 -- Fixed ordering compound queries by nulls_first/nulls_last on MySQL.
...
Columns of the left outer most select statement in a combined query
can be referenced by alias just like by index.
This removes combined query ordering by column index and avoids an
unnecessary usage of RawSQL which causes issues for backends that
specialize the treatment of null ordering.
