Auto-infer instrumentation required helper classes at build time

[sarahchen6]

What Does This Do

Implement methodology to auto-infer instrumentations' required helper classes at build time.

Also migrate a few instrumentations from manual declarations of required helper classes to auto-detecting these classes in order to test the new methodology.

Motivation

Currently, instrumentation helper classes are manually listed for each InstrumenterModule. However, we can instead use Muzzle, which already finds class references for each instrumentation, to automatically discover which helper classes need to be loaded per instrumentation. This is similar to how OTel declares helpers.

Additional Notes

The intention is for all instrumentations to discover required helper classes at build time; however, I wanted to keep the scope of this PR low so that it's easier to review. The rest of the instrumentations will be migrated in follow-up PRs.
