Changelog Entry
Description
This PR is for to solve multiple mcp function calls in a single chat issue, like this #14583 and discussion here
Added
N/A
Changed
changed from "index" to "id" to check whether the call exists, and avoid multiple same function concat together improplerly.
I think the "index" field is useless yet, so maybe "id" is more proper for identity.
