Simplify the `run` macro to avoid sometimes unnecessary dependency on `TyCtxt`. Instead, users can use the new internal method `tcx()`. Additionally, extend the macro to accept closures that may capture variables. These are non-backward compatible changes, but they only affect internal APIs which are provided today as helper functions until we have a stable API to start the compiler.
