feat(openai): handle special tokens for zhipu api (#9323)

* feat(openai): 添加对智谱特殊token的过滤处理

在OpenAIAPIClient中添加对智谱AI特殊token的过滤逻辑，避免不需要的token被输出

* docs(OpenAIApiClient): 添加注释

* refactor(zhipu): 重命名并更新智谱特殊token处理逻辑

将 ZHIPU_SPECIAL_TOKENS_TO_FILTER 重命名为 ZHIPU_RESULT_TOKENS 以更准确描述用途
修改智谱API特殊token处理逻辑，不再过滤而是用**标记结果token
