This approach is fine for this CL, but as we move (or after we move) more things
into LayerImplTestProperties, we should move these getters/setters onto that
class, and only expose TestProperties() getter on LayerImpl (that returns a
lazily allocated LayerImplTestProperties instance).

Done.

This needs to be a unique_ptr.
