Add lib types for JSON.rawJSON, JSON.isRawJSON, and reviver context

Port proposal-json-parse-with-source (ES2025) lib typings onto the Go
tree layout:

- tsc/internal/bundled/source/es2025.json.d.ts (+ generated lib/embed)
- reference from es2025 umbrella + libs.json + LibMap (enummaps.go)
- compiler test and baselines

Preserves RawJSON, JSON.rawJSON, JSON.isRawJSON, and optional
context.source on JSON.parse reviver.

Fixes #61330
