feat: add static reflection

[jolexxa]

• Generate static reflection table for fields and properties from scripts (and applied powerups) containing their names, types, and attributes.
• Generate a static method for each script that allows a receiver object with a generic method to be invoked with the type of the property or field.
• PowerUps that implement interfaces will now add those interfaces to the SuperNodes they are applied to, including any generic interfaces.
• Show how source-only nuget packages can be created/used to share PowerUps between projects and feed those into the consuming package's source generators.
