fix: user custom params should always overwrite other params (#8907)

* fix(aws-bedrock): 未支持自定义参数

* refactor(AnthropicAPIClient): 简化消息创建参数逻辑

移除不必要的MessageCreateParams类型，直接在commonParams中设置stream参数

* refactor(openai): 简化API客户端参数处理逻辑

移除冗余的stream参数分支逻辑，直接在commonParams中设置stream相关参数

* docs(aiCore): 添加注释说明用户自定义参数应覆盖其他参数

* feat(openai): 添加流式输出选项支持

当流式输出启用且提供者支持时，包含stream_options以包含使用情况信息

* fix(openai): 移除冗余的逻辑判断
