Summary:
Pull Request resolved: pytorch#2067

# context
* convert `FeatureProcessedEmbeddingBagCollection` to custom op in IR export
* add serialization and deserialization function for FPEBC
* add an API for the `FeatureProcessorInterface` to export necessary paramters for create an instance
* use this API (`get_init_kwargs`) in the serialize and deserialize functions to flatten and unflatten the feature processor

# details
1. Added `FPEBCMetadata` schema for FP_EBC, use a `fp_json` string to store the necessary paramters
2. Added `FPEBCJsonSerializer`, converted the init_kwargs to json string and store in the `fp_json` field in the metadata
3. Added a fqn check for `serialized_fqns`, so that when a higher-level module is serialized, the lower-level module can be skipped (it's already included in the higher-level module)
4. Added an API called `get_init_kwargs` for `FeatureProcessorsCollection` and `FeatureProcessor`, and use a `FeatureProcessorNameMap` to map the classname to the feature processor class
5. Added `_non_strict_exporting_forward` function for FPEBC so that in non_strict IR export it goes to the custom_op logic
