optimize: unify seata jsonParser

## Why you need it?

The seata tcc module and the saga module each define jsonParser, and the default parsers are inconsistent. One is jackson and the other is fastjson. We should unify these into the common module.

In addition, jsonParser can be considered as a serialization implementation. Can it be moved directly to the serialization module?

seata tcc模块和saga模块都各自定义了jsonParser，并且默认的parser不一致，一个是jackson，一个是fastjson，我们应该统一这里到通用模块。

另外jsonParser可以认为是序列化实现，是不是可以直接移动到序列化模块。

Start by locating and comparing the jsonParser definitions in the TCC and Saga modules, including their Jackson and Fastjson defaults. Then inspect the common and serialization modules to determine the appropriate destination; done means the parser has one consistent implementation and both modules use it.
