gh-92036: Fix gc_fini_untrack() (GH-92037)
Fix a crash in subinterpreters related to the garbage collector. When
a subinterpreter is deleted, untrack all objects tracked by its GC.
To prevent a crash in deallocator functions expecting objects to be
tracked by the GC, leak a strong reference to these objects on
purpose, so they are never deleted and their deallocator functions
are not called.
(cherry picked from commit 14243369b5f80613628a565c224bba7fb3fcacd8)
