[Python] unify DataClassSerializer and ComplexObjectSerializer

[chaokunyang]

Feature Request

Currently ComplexObjectSerializer is used for xlang serializaiton, and DataClassSerializer is used for pure python serialization.

Both serializers are used for struct class, we should merge those serializers into one like we did in #2146 .

And DataClassSerializer used codegen tenchniques to speed serialization, this could be used in xlang serialization too
