Builds the call builders for the provider's platform. Under CD9 (plan 12) one set of builders serves both
platforms — the SQL lives in the spWorkQueue* procedures and only the call syntax differs, which the context's
dialect supplies — so the factory's job is to refuse a platform the procedures have not been written for. If a
platform is added to DatabasePlatform later, the never assignment fails the build, which is the intent.
