merge: #3497

3497: Remove unused schema variant def module and unused auth prototype code (ENG-2426) r=nickgerace a=nickgerace

## Description

`SchemaVariantDefinition` no longer exists in the new engine, so this PR removes its remains from the dal.

## Additional Note

This is a follow-up to #3474.
