refactor accuracy eval script to be organized by hardware

Summary:

We have a many-to-many mapping of recipe to device it can run on.
Reorganizing the accuracy script to reflect this, since we don't have a
machine that can run all the workflows.

Test Plan:

```
// test on h100
benchmarks/quantization/eval_accuracy_for_readme.sh h100
```
