[Python 3.11] Fix Segfault

[jackyk02]

Issue
Segfault due to Python 3.11 changes to object layout and memory allocation methods.

Background
Python 3.11 introduced changes to optimize CPython. One of the significant changes, as mentioned in this PR, modifies the object layout to place pointers to dict and values immediately before the GC header. This change potentially affected the memory layout of custom python objects.

Before:

After:

Moreover, this commit removed _PyObject_GC_Calloc and _PyObject_GC_Malloc, affecting the memory allocation for objects that participate in garbage collection.

Solution
The new memory allocation relies on PyObject_New instead of PyObject_GC_New.

Updates in this PR
The earlier PR #293 only updates the memory allocation for convert_C_port_to_py. However, updates are also necessary for convert_C_mode_to_py and convert_C_tag_to_py.

Test
./gradlew targetTest -Ptarget=Python is expected to pass now with the modifications introduced in this PR.

This is probably a necessary part of supporting Python 3.11, but I have no idea what else would be required and we would probably have to either require Python 3.11 or find a way to support both 3.10 and 3.11. I suspect eventually we will need to support later versions of Python, so I don't know what to do with this either.
