This config was deprecated in favor of Int8DynamicActivationIntxWeightConfig.
Remove the class definition, handler, and all references from imports, tests,
QAT code, benchmarks, and documentation. Update QAT docs to reference
Int4WeightOnlyConfig as the example base config.

Remove the config class, its supporting classes (Float8ObservedLinear,
Float8ObservedSoftmax, Float8QuantizedSoftmax), the handler function,
and all references from imports and tests.

This config was deprecated and scheduled for deletion. Remove the class
definition, handler, and all references from imports, tests, benchmarks,
and the autoround eval script. This also removes the entire BC import
block from quant_api.py since all prototype configs have been removed.

Summary:

This PR removes CUSTOM_PARAM_QUANTIZATION_SUPPORTED_CONFIGS, in favor of
using `inspect.signature` to ensure that the given handler has a
parameter_name kwarg we can use to pass in the param fqn.

Test Plan:
```
pytest test/quantization/test_quant_api -k fqn
```

Enable parameter-level quantization by accepting a parameter_name kwarg,
using getattr/setattr instead of hard-coded module.weight, and switching
to _module_extra_repr with partial for flexible repr.
