Deactivate the tracking of gradients in sampling functions within OpInfos (#68522)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68522
Some OpInfos were inadvertibly generating samples with `grad_fn`. For
example, when using functions like `transpose()` or `conj()` on the
inputs to generate transposed or conjugated inputs. This PR corrects
this and deactivates the tracking of gradients in all the sampling
functions.
