Summary:
- Fixes https://github.com/pytorch/pytorch/issues/39557 .
- Related https://github.com/pytorch/pytorch/issues/38558 .
- Simplifed `void bernoulli_kernel(TensorIterator& iter, double p_, RNG gen)` in `cuda/DistributionTemplates.h` by using `uniform_and_transform`.
- Unified `void bernoulli_kernel(TensorIterator& iter, double p_, RNG gen)` with other kernels in `cuda/DistributionTemplates.h`.
