This simplifies the use case for mixed build users. Instead of having to remember to call img_from_target_files.py after this script, they can use this flag to automatically create the IMG package. Also includes an update to super_empty.img logic. The super_empty.img is now always created for dynamic-partition builds. The flag now only controls copying the super_empty.img to a user-provided location. Bug: 129976345 Test: Ran merge_target_files.py using --output-img and --output-super-empty and inspected the resulting img zip and super_empty.img.
