remove IntWrapper

[jeffdaily]

I could not access https://github.com/NVlabs/cub/issues/172 to understand whether IntWrapper was still necessary but the comment is from 5 years ago and causes problems for the ROCm build.

@bottler thank you for importing. The CI is failing due to undefined symbol. I don't know how this is related to the PR change.

from pytorch3d import _C
ImportError: /home/runner/.conda/envs/env/conda-bld/pytorch3d_1743032983446/_test_env_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_/lib/python3.12/site-packages/pytorch3d/_C.cpython-312-x86_64-linux-gnu.so: undefined symbol: _ZN3c105ErrorC2ENS_14SourceLocationESs

which is

c10::Error::Error(c10::SourceLocation, std::basic_string<char, std::char_traits<char>, std::allocator<char> >)

That's not the fault of this PR. CI is failing like that on main and currently fails on the previous commit, although it didn't originally fail when that commit landed. So something external has changed which breaks the github action.

I can see meta's internal CI is fine with this PR.

[jeffdaily]

Does that mean we can merge this PR even though other CI failures exist?
