Seata TCC模式下commit方法和rollback方法branchType缺失

[Yang-xingchen]

Ⅰ. Issue Description

在使用TCC模式下时，调用到commit方法和rollback方法时，方法内BusinessActionContext.getBranchType()得到内容为null。

Ⅱ. Describe what happened

If there is an exception, please attach the exception trace:

Ⅲ. Describe what you expected to happen

Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. 接口使用@LocalTCC注解
2. prepare方法使用@TwoPhaseBusinessAction注解,
3. prepare方法、commit方法、rollback方法第一个参数均为BusinessActionContext
4. prepare方法可以正常获取到branchType为TCC，commit方法和rollback方法获取branchType为null

Minimal yet complete reproducer code (or URL to code):

Ⅴ. Anything else we need to know?

目前调试发现在org.apache.seata.rm.tcc.TCCResourceManager中branchCommit方法和branchRollback方法参数中有branchType值且取值正常，但方法体中未使用该值(包括创建BusinessActionContext对象)。
当前代码仓库中也未使用该值TCCResourceManager

Ⅵ. Environment:

• JDK version(e.g. java -version): 21
• Seata client/server version: client: 2.1.0 server: 2.2.0
• Database version: 未使用
• OS(e.g. uname -a): Linux zk1 5.18.15-1.el7.elrepo.x86_64 fescar init #1 SMP PREEMPT_DYNAMIC Thu Jul 28 09:26:15 EDT 2022 x86_64 x86_64 x86_64 GNU/Linux

I suspect this is a bug. Could you submit a PR to fix this issue?

@YongGoose ok，I am still learning Seata and not very familiar with it yet. You can fix it.
