This PR marks the context argument of `ReaderT` as borrowed, causing a wide spread of useful borrow annotations throughout the entire meta stack which reduces RC pressure. This introduces a crucial new behavior: When modifying `ReaderT` context, e.g. through `withReader` this will almost always cause an allocation. Given that the `ReaderT` context is frequently used in a non-linear fashion anyways we think this is an acceptable behavior.
