[Feature Request] Add native web search toggle for VolcEngine(Doubao), just like Qwen & Vertex Gemini

[3173757283]

Qwen supports native web search via enable_search: true in API request, and Vertex Gemini has built-in search switch on Dify.
VolcEngine Doubao also has official native web search capability, but Dify’s VolcEngine provider lacks the toggle option now.
Please add an Enable Native Official Web Search checkbox for VolcEngine config, same design as Qwen/Gemini.
Could you inform the planned release schedule? Thanks.
