Create a builder divorced from the ReflectionContext so that MetadataSources can be created in other contexts, such as emitting private heap metadata during IRGen, where we'll have to record the layout of captures and how to get metadata for generic arguments in order to construct typerefs of the captures, etc. Add Parent, Metadata capture, and Impossible metadata sources.
