…ction. Looks like # caused a regression: the compiler appears to be dead-code-stripping the classes we emit to contain test content records. This PR changes the design back to using a protocol so that the members we need are always covered by `@_alwaysEmitConformanceMetadata`. This makes `_TestDiscovery` a little harder to use with legacy lookup, but it's all experimental and eventually going to be removed anyway. Resolves rdar://146809312.
