RFR: 8358772: Template-Framework Library: Primitive Types [v5]

[Emanuel Peter]

> I would like to add primitive type support to the template framework library.
> 
> In follow-up work, we will use these types in random expression generation - but they can also already be useful on their own now.
> 
> I encountered an issue with some methods that return `Token` from the `TemplateFramework`, such as `Hook.insert` and `addDataName`. Since `Token` was package private, this class could not be used in some places where automatic type inference is required. I now refactored the code, so that the `Token` is just an empty interface, and all the methods are moved to a separate class `TokenParser`.
