implement NumPy-like functionality maximum, minimum (#42579)
Summary:
Related to https://github.com/pytorch/pytorch/issues/38349
Implement NumPy-like functions `maximum` and `minimum`.
The `maximum` and `minimum` functions compute input tensors element-wise, returning a new array with the element-wise maxima/minima.
If one of the elements being compared is a NaN, then that element is returned, both `maximum` and `minimum` functions do not support complex inputs.
This PR also promotes the overloaded versions of torch.max and torch.min, by re-dispatching binary `torch.max` and `torch.min` to `torch.maximum` and `torch.minimum`.
