bpo-44525: Copy free variables in bytecode to allow calls to inner functions to be specialized (GH-29595)
* Make internal APIs that take PyFrameConstructor take a PyFunctionObject instead.
* Add reference to function to frame, borrow references to builtins and globals.
* Add COPY_FREE_VARS instruction to allow specialization of calls to inner functions.
