Add a lot of dimname overloads (#26636)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/26636
This PR defines a lot of dimname overloads so that when named tensor
support is added for those operators, we will not have to modify the
autogenerated TensorMethods.h, thereby avoiding potential merge
conflicts in the future.
Overloads were added for the following:
- all
- any
- argmax
- argmin
- cumsum
- cumprod
- index_copy
- kthvalue
- mode
- permute
- squeeze
- index_add
- index_fill
- scatter
- scatter_add
- index_select
- gather
- sort
- argsort
Test Plan: - [namedtensor ci]
