Gets a list of generic parameters.
Gets a list of generic parameters. This is because the generic parameters of a class cannot be used directly in the return type, and need to be converted.

Subclasses should override the method and return the final result abstract syntax tree, or an abstract syntax tree close to the final result.
Subclasses should override the method and return the final result abstract syntax tree, or an abstract syntax tree close to the final result. When the macro implementation is very simple, we don't need to use this method, so we don't need to implement it. When there are many macro input parameters, we will not use this method temporarily because we need to pass parameters.
