Tracking issue: Resolve TypeScript declaration lint errors

The purpose of this issue is to track tasks for resolving lint errors in our TypeScript declaration files.

The issue does not identify specific declaration files, lint rules, tests, or entry points. Start by locating the TypeScript declaration files and the lint configuration, then determine the set of errors to address; done means the declaration lint checks pass.
