Lifter.Gil_fallback_lifterA Lifter implementation that acts as a proxy to another lifter (TLLifter), while also keeping a Gil_lifter updated alongside.
TLLifter can access the GIL lifter and its state via Gil_lifter_with_state.
Note that if the GIL lifter gives anything other than Stop when handling a command, it is considered skipped, and TLLifter won't be asked to handle it.
