Fix index_put when tensor length > int_max (#33753)
Summary:
This PR would fix https://github.com/pytorch/pytorch/issues/33345.
The original CUDA kernel looks good. I changed most appearances of `int` to `int64_t` to avoid the CUDA memory access issue. Removed the two `TORCH_CHECK`. Added a unit test.
