Compress xcframework to let sonatype sign it (#49753)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49753

Sonatype cannot sign folders. It needs a file to be signed.
To make it happen, we are compressing the xcframeworks and the dSYM with tar, and we are uploading those files instead of the folders

I also observed that the cache keys were not computed correctly, so I'm fixing them.

## Changelog:
[Internal] - use tar.gz instad of folders for dSYM and xcframeworks
