Fixed #33282 -- Fixed a crash when OR'ing subquery and aggregation lookups.
...
As a QuerySet resolves to Query the outer column references grouping logic
should be defined on the latter and proxied from Subquery for the cases where
get_group_by_cols is called on unresolved expressions.
Thanks Antonio Terceiro for the report and initial patch.

Refs #26430 -- Re-introduced empty aggregation optimization.
...
The introduction of the Expression.empty_aggregate_value interface
allows the compilation stage to enable the EmptyResultSet optimization
if all the aggregates expressions implement it.
This also removes unnecessary RegrCount/Count.convert_value() methods.
Disabling the empty result set aggregation optimization when it wasn't
appropriate prevented None returned for a Count aggregation value.
Thanks Nick Pope for the review.

Fixed #32632 , Fixed #32657 -- Removed flawed support for Subquery deconstruction.
...
Subquery deconstruction support required implementing complex and
expensive equality rules for sql.Query objects for little benefit as
the latter cannot themselves be made deconstructible to their reference
to model classes.
Making Expression @deconstructible and not BaseExpression allows
interested parties to conform to the "expression" API even if they are
not deconstructible as it's only a requirement for expressions allowed
in Model fields and meta options (e.g. constraints, indexes).
Thanks Phillip Cutter for the report.

Previously unresolved Value() instances were only allowed to be
compiled if they weren't initialized with an output_field.
Given the usage of unresolved Value() instances is relatively common in
as_sql() overrides it's less controversial to add explicit support for
this previously undefined behavior now and revisit whether or not it
should be deprecated in the future.
