PyObjBag built code object constants from a Context alone, and its
frozenset arm was unimplemented!(), so ctx.new_code() panicked on code
containing a frozenset constant such as `x in {1, 2, 3}`.
IntoCodeObject now takes a VirtualMachine and uses PyVmBag for bytecode
and frozen code objects. Context::new_code, PyObjBag and
AsBag for &Context are removed; callers use VirtualMachine::new_code.

* Borrow tp_descr_get/tp_init arguments and by-value public helpers
- DescrGetFunc and GetDescriptor::descr_get take
(&PyObject, Option<&PyObject>, Option<&PyObject>); impls call
.to_owned() where they store or return an argument.
- InitFunc takes &PyObject and Initializer::init takes &Py<Self>.
- VirtualMachine::get_attribute_opt, print_exception,
call_get_descriptor(_specific) and other helpers flagged by
clippy::needless_pass_by_value take &PyObject / &Py<T>; callers in
crates/, examples/ and tests/ drop the clones made for the call.

* Pass the borrowed zelf to internal_close in WindowsConsoleIO init
Assisted-by: Claude Code:claude-opus-5-5
* Fix borrowed signatures missed by the rebase
OrderedDict.init, classmethod_descriptor.descr_get, and the warnings
get_attribute_opt callers still used owned handles.
