Registers a BindingToNormalizedNodeCodec instance as an osgi service. To quote jdoc:
"* This method is called via blueprint to register a BindingToNormalizedNodeCodec instance with the OSGI

• service registry. This is done in code instead of directly via blueprint because the BindingToNormalizedNodeCodec
• instance must be advertised with the actual class for backwards compatibility with CSS modules and blueprint
• will try to create a proxy wrapper which is problematic with BindingToNormalizedNodeCodec because it's final
• and has final methods which can't be proxied."
