📄 Description

The two main features added in this PR are LIB_MEMBER_FUNCTION and LIB_OVERLOADED_MEMBER_FUNCTION, which are similar to LIB_FUNCTION but hopefully should work with class member functions instead. I'm not sure yet if they actually work as I haven't had the chance to test it yet, since the stubbed libSceJson library isn't used by any game I know of, which is what I made these for in the first place.
The PR also contains the stubbed libSceJson library itself with hopefully correct classes and function signatures (except the return values) based on me demangling the exported function names, and a small continuation of my earlier RegisterLib PR, where I've apparently missed a few libraries (which could have gone into a different PR I guess, but it's only just me renaming stuff so it's not too important).
