What it does
This PR wraps class-derived objects in the VS Code API inside a proxy. Additionally, any functions that are defined in the class prototype are bound to the object in question. This guards against the misuse of object methods as pure functions. As an additional bonus, clients no longer have access to the internals of the API objects like the main/ext proxies.
Fixes #13522

How to test
This one is hard to test comprehensively as it covers a large code surface. The best way is to work with a wide variety of plugins to verify that we have not missed any subtle interactions with the API object implementation.
