[EdgeML] Remove dependency on all_mobile_model_configs.yaml from pt_operator_library BUCK rule (#99122)
Summary: Removes the dependency on the unified YAML file
Test Plan:
Smoke test via some caffe2 tests.
```
buck2 run xplat/caffe2:supported_mobile_models_test
```
Build a major FoA app that uses model tracing and confirm it still works.
```
buck2 build fb4a
```
CI/CD for the rest. If operator tracing / bundling was broken, I'd hope in the 1000+ tests spawned by this change should catch it.
