Prepare to add some Dimname/DimnameList overloads (#25405)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/25405
This PR adds schemas to native_functions.yaml, core/Tensor.h, and
core/TensorMethods.h for Dimname/DimnameList overloads for the following
functions:
- min, max, max_values, min_values
- mean, meadian
- logsumexp, std, var, norm
The actual implementations will come in a later PR. I am accumulating
all the addtional schemas and changes to core/{Tensor|TensorMethods}.h
in this PR so that there is only one point of failure for potential
merge conflicts.
Test Plan: - Check that all pytorch builds still build. [namedtensor ci]
