add operator-range argument to the op bench (#30051)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/30051
This argument takes hyphen delimited start and end chars to filter operators. If the first character of an operator is in the start and end range, it will be tested. Otherwise skipped.
(Note: this ignores all push blocking failures!)
Test Plan:
```
buck run mode/opt caffe2/benchmarks/operator_benchmark:benchmark_all_test -- --iterations 1 --operator_range b-c
