Include call IDs in MCP requests and clarify metadata config (#37477)

## What changed

- Add the tool call ID to `_meta.callId` for every MCP tool request.
- Rename `features.tool_registry.include_tool_metadata` to
  `features.tool_registry.turn_metadata_includes_tool_info` to clarify that the
  setting controls authoritative tool information in per-turn metadata.
- Update config parsing, schema generation, and session config locking for the
  renamed setting.

## Testing

- Cover `callId` metadata for custom, plugin, and Codex Apps MCP calls.
- Update strict-config, config-loading, feature-config, and config-lock tests for
  the renamed setting.
