random_() is not supported for bfloat16 CUDA tensors on Windows

[pbelevich]

This is a known issue, that requires further investigation, currently calling any random_() method on bfloat16 CUDA tensor on Windows makes CUDA context invalid, all subsequent CUDA calls fail with 'CUDA error: unspecified launch failure'

Assignee, please look for "TODO: https://github.com/pytorch/pytorch/issues/33793" in the source code
