[fix] self._default_scores was not tracked by tensorflow graph when it's as a class property, which caused fail saving.
Sinc _default_scores was always tf.constant([], dtypes.int64), so replace it totally instead of _track_trackable it.
[fix] Inherit abc.ABC may cause metaclass conflict with other Tensorflow class.
[fix] hkv_hashtable_ops_test has duplicate variable name when test both CPU and GPU device.
[fix] Compatible with HKV asserting when init_capacity is smaller than max_bucket_size
