This PR adds support for in-place list updates (append/prepend) for
array-based features in DynamoDB online store, addressing issue feast-dev#5687.

Key changes:
- Add update_online_store() and update_online_store_async() methods to
  FeatureStore for list operations on existing feature values
- Implement read-modify-write pattern in DynamoDB store to handle list
  operations while maintaining compatibility with existing protobuf
  serialization format
- Add comprehensive tests for list append, prepend, mixed operations,
  and new entity handling

The implementation uses a read-modify-write approach because existing
data is stored as serialized protobuf bytes, not native DynamoDB lists.
This maintains backward compatibility with existing online_read methods.

Per reviewer feedback, removed the synchronous update_online_store method
and renamed update_online_store_async to update_online_store.
