[issue46561] Descriptor resolution should own arguments passed to descriptors

[Maxwell Bernstein]

New submission from Maxwell Bernstein <tekk.nolagi at gmail.com>:

Currently the descriptor (self) argument to __get__ is passed borrowed, since _PyType_LookupId returns a borrowed reference (see _PyObject_LookupSpecial and lookup_maybe_method in Objects/typeobject.c). This should instead own the reference.
