[improvement](be) Add optional structured output for batched AI functions
(#69302)
### What problem does this PR solve?
doc: https://github.com/apache/doris-website/pull/4442
Problem Summary:
Improve batched AI function output reliability by adding optional
structured output constraints and validating the returned results. Reuse
static format definitions and preserve embedded NUL characters when
parsing responses.
Add the resource property `ai.enable_structured_output` (default:
`true`). When disabled, requests remain batched and rely on the system
prompt without provider format fields.
For example, OpenAI Chat Completions requests include:
```json
{
"response_format": {
"type": "json_schema",
"json_schema": {
"name": "ai_batch_result",
"strict": true,
"schema": {
"type": "object",
"properties": {"results": {"type": "array", "items": {"type":
"string"}}},
"required": ["results"],
"additionalProperties": false
}
}
}
}
```
### Release note
Add ai.enable_structured_output (default true). Disabling it omits
provider format fields while retaining batching, prompts and result
validation.
