A few notes from the latest tensorflow builds 2.15

This is the first time I'm trying to do a CFEP-03 copy... I looked at the build logs and noted a few minor things, that have to be pre-existing (given the changes here):
```
WARNING: Exact overlap between include/tensorflow/core/platform/ctstring.h in packages libtensorflow_cc and libtensorflow
WARNING: Exact overlap between include/tensorflow/core/platform/ctstring_internal.h in packages libtensorflow_cc and libtensorflow

WARNING: Exact overlap between lib/libtensorflow_framework.2.dylib in packages libtensorflow_cc and libtensorflow
WARNING: Exact overlap between lib/libtensorflow_framework.dylib in packages libtensorflow_cc and libtensorflow
```

Also why are we putting a patch (that conda patches again) into `$PREFIX/include`? Seems very strange
```
include/third_party/pybind11_protobuf/0001-Add-Python-include-path.patch (text): Patching
```

In any case, I wanted to copy the packages, but I haven't managed to run the [commands](https://github.com/conda-forge/tensorflow-feedstock/pull/347#issuecomment-1809390975), because I cannot pass through authentication of the anaconda client. I have an account, I double-checked (then updated) my password, I've tried various ways to spell my identity (username/email), and I haven't managed to get through yet.
