We need a serializer for storing a list of component types in yaml

Currently if you need a list of components as a datafield they are either stored as strings and converted with TryGetRegistration

or even worse as a whole ComponentRegistry when the values of the datafields inside the components aren't even needed.

There even seems to be CompRegistryQueryEnumerator which is used to find entities with the components from a registry.
