GH-92955: fix memory leak in code object lines and positions iterators

Closes #92955

@vstinner @erlend-aasland
I am not sure that we need to handle all these cases,
or is it better to wait for approval for converting static types into heap types from SC

[kumaraditya303]

These are the last static types which are accessible from python which are not finalized by the interpreter exit in core objects (Objects directory).

Also IIUC Heap types should be only used in extension modules not for interpreter core objects.

From PEP 687:

Static types that do not need module state access, and have no other reason to be converted, should stay static.

[kumaraditya303]

Just to be clear this PR has nothing to do with conversion of static types to heap types. This PR only fixes a memory leak as static type was not finalized and is now finalized like other static types.

That's nice

About heap types..

I just asked about one of Victor's last suggestions.
: #91727 (comment)

[kumaraditya303]

Victor: Add the type to the static_types list in object.c (I tried to add all types there),

I am finishing off his work of adding all static types which need to be finalized at exit and these are the last ones left.

[corona10]

Since this will be the last change under Objects/*.c, I am happy to approve this change.

Thanks @corona10
