[ios] Reland "[ios] use python script to generate extension safe frameworks and code sign them" #46004" (#46014)

Relands #45781
The Flutter.framework and the sim folders are mistakenly added to the artifact, this PR removed those files along with re-landing the original changes 

flutter/flutter#134966 should pass with this change.
