Create super_empty.img using Soong
The build rule for this .img file will be created in super_image. It
will use the a minimized file returned by `buildMiscInfo` without any
partition information. This file will be disted in target_files.zip
Bug: 390192334
Test: Verified that this file is bit-identical between make and soong
for aosp_cf_x86_64_phone
