[PATCH] D68629: [llvm-exegesis] Finish plumbing the `Config` field.

Right now there are no snippet generators that emit the `Config` Field,
but I plan to add it to investigate LEA operands for PR32326.

What was broken was:

- `Config` Was not propagated up until the BenchmarkResult::Key.
- Clustering should really consider different configs as measuring different things, so we should stabilize on (Opcode, Config) instead of just Opcode.
