AVL benchmark fix

[kurtisc]

Blocks #788 , which aims for a more comprehensive solution

What

Fixes the AVL benchmark, which is currently broken.

Why

The benchmark isn't built unless the "bench" feature is passed, so the compilation issues aren't caught in CI

How

• Exposes the used methods/types
• Uses ArcResolver in the benchmark code

Manually Testing
