Add Function Name, Constants, Globals and Local Variables to RAnnotatedCode (#17429)
* Annotation for function name (#17204)
* Annotations for Constant Variables and Global Variables for the decompiler (#17281)
* Annotation For Function Variables (#17375)
* function variable annotation added (includes local variable and function parameter)
* API for checking if an annotation is a reference or function variable. (#17386)
* Update docs in annotate code API  (#17397)
* Unit tests for annotated code API (#17403)
