Split the diagnostic emitter into a separate emitter (regietered with Clang) and listener (registered with the emitter). The purpose of this split is to make the Clang emitter not depend on the `Check::Context`, so that we can use it, and hence the same Clang instance, with multiple `Check::Context`s. A fallback listener is registered to collect and emit any diagnostics produced while we don't have a `Check::Context` registered with the emitter. Assisted-by: Gemini via Antigravity
