Complex Autograd support for torch.dist is currently untested #53516
Description
Remove the existing method_tests (that aren't currently testing complex) and add an OpInfo test instead.
>>> x = torch.randn(4, dtype=torch.cdouble, requires_grad=True)
>>> y = torch.randn(4, dtype=torch.cdouble, requires_grad=True)
>>> torch.autograd.gradcheck(torch.dist, [x, y, 3.5])
True
