This pulls EmbeddedInstanceManager, EmbeddedServiceRunner, and
EmbeddedServiceInfo out of the //services/service_manager/embedder
target and into the client library, where they belong. These types
are used only by client code to facilitate embedding services within
other services and they require no linkage to the Service Manager
implementation.
