co_linetable, co_exceptiontable and co_name as objects on PyCode;
build co_code and the varnames/cellvars/freevars tuples lazily in

const_cache_insert) to builtins/code/const_cache.rs.

field objects to MarshalBag::make_code through CodeFields.

after them; drop the generator part of insert_prefix_instructions.
- Add PyCode::first_traceable (_co_firsttraceable) for
_PyFrame_IsIncomplete and sys.monitoring.
- Follow the CPython DISABLE branches in sys.monitoring, the
check_matched signature in warnings, the 3.15 % format error
messages for str and bytes, code_returns_only_none, and the FOR_ITER
stack analysis.
- Compute IMPORT_NAME flags with in_exception_handler.
- Replace the linetable/exceptiontable byte tests in codegen with
dis(show_positions=True) insta snapshots in _opcode.
- Remove the opcode metadata verification tooling, byte-exact
scripts, private cache tests and redundant snippets.
