Add node macro support for injecting nodes into global scope (#4221)

Browse Source 
* Macro support

* Preprocessor support

* Allow Cow str as scope name

* Use Passthrough node to work around compiler auto wrapping the producer node and invalidating the node id

* Stable NodeIds

* Less hacky but with bad performace

* Remove Cow from RegistryValueSource::Scope

* Connect scope injections to the inner network export
