Add batchnorm running calc weight to porting script

[amyeroberts]

What does this PR do?

Add two weight name mappings for PyTorch -> TensorFlow necessary for cross-loading weights for batchnorm layers which have been trained with tracking_running_stats=True.

This was necessary for cross-loading weights for the ResNet and RegNet ports. #17536 , #17554

Thanks a lot for diving into this. I would very very very much prefer if we could that rename in the functions that change the weights (and maybe reshape) as this renaming gamma/beta has been a huge pain in the butt for many contributors (and we actually wanted to get rid of it when we find a way to make it in a BC fashion).

@sgugger I'll open a follow-up PR to address your comments.

Actually, I misread the file where it's modified 😅
It's fine for the conversion like this, it's the code in modeling_utils that does this I don't want (like here). Sorry I didn't pay close enough attention.
