Search-on-views only works on view definitions with $addFields and/or $match in the definition. We need to add a test that confirms an extension desugars and applies to the search when the extension is in the view definition.

However, we currently don't have a test extension that desugars into only $addField and/or $match. This ticket should add such an extension and add a basic test to the `with_mongot/e2e/views/vector_search` directory that confirms behavior of the extension in the view definition.
