Remove native_functions.yaml dependency from DistributionBernoulli.cu (#67721)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/67721
This moves the operator calls (`expand_inplace` and `to(kCUDA)`) into
`bernoulli_impl_` which is shared between CPU and CUDA. So that the
cuda code only needs to generates random numbers and nothing else.
The other changes are just rearranging includes to avoid including
`Tensor.h`.
