Improve Sqlite support for sub-queries and CTE's (#1816)
* reproduce incorrect nullability for materialized views

* split ephemeral/index-only table handling from real table handling

* add test for literal null, expect nullability to be identified from table information

* gather interpreter state into a struct, no change in behaviour

* prevent infinite loops that could arise once branching is supported

* track nullability alongside the datatype instead of in a separate lookup

* implement basic comprehension of branching opcodes

* fix datatype calculation of aggregates which are never 'stepped' through

* implement coroutine and return operations, including tracking of 'actual' integer value stored in the register by Integer/InitCoroutine/Yield operations.

* strip unnecessary history field out

* Modify variable test to expect bind-variable outputs to be nullable, rather than unknown

* add partially commented-out union tests, simplify code to satisfy simplest union case

* fix unit test incorrectly expecting primary keys to be implicitly not-null

* add failing test for recursive tables

* add logging of query explain plan

* track explain plan execution history

* broken RowData implementation (doesn't alias)

* Implement OpenPseudo tables as an alias of a register value

* fix comment

* clean up logging code warnings

* use cfg to omit QueryPlanLogger unless sqlite feature is used
