Resolving TODOs for from_unique_ptr void_cast_raw_ptr. Adding test to exercise the path through cast. The path through init.h is missing a test that would fail if the flag is incorrect. The plan is to systematically cover all situations (there are many that are not exercised for shared_from_this).

Use casting to void * to evade to shared_from_this mechanism only if pointee_depends_on_holder_owner, but currently only for from_raw_ptr_take_ownership.

Simpler and safe implementation based on new requirement: C++ (outside of the Python object) needs to hold a shared_ptr before shared_from_this is called. This is more similar to the existing implementation on current smart_holder HEAD, but still uses a weak_ptr to always return the same shared_ptr as long as C++ does not let it expire.

smart_holder_poc.h: type-erase raw_ptr before passing to shared_ptr::reset, to not trigger populating the shared_from_this weak_ptr. This way the only way the weak_ptr is populated is through loaded_as_shared_ptr. Breaks all but one test in test_class_sh_trampoline_shared_from_this.py, now marked skip WIP to test everything else with the GitHub CI.

Leveraging new noop_deleter_acting_as_weak_ptr_owner to retrieve released vptr.
...
The placeholder `vptr` is never exposed anymore, therefore the externally visible `use_count`s are more intuitive.

First fully successful attempt to make shared_from_this and trampolines play nicely.
...
Now also passes the open_spiel iterated_prisoners_dilemma_test ASAN clean, in addition to all pybind11 and PyCLIF unit tests.
The problem was that calling `std::shared_ptr<void>::reset()` with a `void` pointer cannot possibly update the `shared_from_this` `weak_ptr`.
The solution is to store a `shd_ptr_reset` function pointer in `guarded_deleter` (similar in idea to the stored function pointer for calling `delete`).
This commit still includes all debugging code, i.e. is "dirty". The code will be cleaned up after the GitHub CI is fully successful.
