remove "deannotate" from column_property expression
Fixed issue where using a :func:`_orm.column_property` construct containing a subquery against an already-mapped column attribute would not correctly apply ORM-compilation behaviors to the subquery, including that the "IN" expression added for a single-table inherits expression would fail to be included. This fix involves a few tweaks in the ORM adaptation logic, including a missing "parententity" adaptation on the mapper side. The specific mechanics here have a lot of moving parts so we will continue to add tests to assert these cases. In particular a more complete test for issue #2316 is added that was relying upon the deannotate happening here. Fixes: #8064 Change-Id: Ia85dd12dcf6e7c002b30de4a27d7aa66cb3cd20e
