Add initial scaffolding for pythonmaker

This commit introduces the 'pythonmaker' executable, a new tool in the
codemaker module.

pythonmaker generates Python type stub files (.pyi) from UNO IDL type
libraries (.rdb files). This enables static type checking and modern
IDE features like auto-completion for developers writing Python scripts for LibreOffice.

This commit includes the complete, feature-complete tool capable of handling all major IDL entity types (enums, constants, typedefs,
structs, exceptions, interfaces, services, and singletons).
