Do not use deprecated `at::Tensor::type()`

Summary:
X-link: https://github.com/facebookexternal/vizard/pull/5

X-link: https://github.com/fairinternal/egohowto/pull/72

Pull Request resolved: https://github.com/facebookresearch/d2go/pull/680

Replace `tensor.type().scalarType()` with `tensor.scalar_type()` (this be able to get rid of the cast function in https://github.com/pytorch/pytorch/pull/139358 )

Remove extraneous braces around lambdas
