GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython (GH-103083) 
* The majority of the monitoring code is in instrumentation.c

* The new instrumentation bytecodes are in bytecodes.c

* legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs

GH-96793: Change `FOR_ITER` to not pop the iterator on exhaustion. (GH-96801)
