Mark `c10d::~NCCLUtils` as noexcept (#29118)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/29118
It's never a good idea to throw from a destructor and per #28288 we
can't use `std::make_shared` on a class with a `noexcept(false)`
destructor.
To fix this, we `abort` instead of throw from the `NCCLComm` destructor.
Closes #28288.
