This CL is a preliminary work to move the description generation of objects that are not V8 specific to the Embedder. Until now, the description for Nodes and Trusted Types was generated by V8 what was problematic, since Blink (not V8) is who has access to the information required for the description.
Once the refactoring is complete the existing descriptionForNode and descriptionForTrustedType can be deleted from V8.
