971df458 - Reland of "Python binding to set/get CUDA rng state offset" (#99565)

Reland of "Python binding to set/get CUDA rng state offset" (#99565) Why? * To reduce the latency of hot path in https://github.com/pytorch/pytorch/pull/97377 Concern - I had to add `set_offset` in all instances of `GeneratorImpl`. I don't know if there is a better way. ~~~~ import torch torch.cuda.manual_seed(123) print(torch.cuda.get_rng_state()) torch.cuda.set_rng_state_offset(40) print(torch.cuda.get_rng_state()) tensor([123, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], dtype=torch.uint8) tensor([123, 0, 0, 0, 0, 0, 0, 0, 40, 0, 0, 0, 0, 0, 0, 0], dtype=torch.uint8) ~~~~ Reland of https://github.com/pytorch/pytorch/pull/98965 (cherry picked from commit 8214fe07e8a200e0fe9ca4264bb6fca985c4911e) Pull Request resolved: https://github.com/pytorch/pytorch/pull/99565 Approved by: https://github.com/anijain2305
