`torch.prod` backward for complex types. (#48125)
Summary:
Fixes https://github.com/pytorch/pytorch/issues/53511
torch.det does depend on torch.prod, which in turn depends on several other functions, and they also depend on torch.prod, so there is a circular relationship, hence this PR will enable complex backward support for several functions at once.
