Add "with-license" rule to generate public AOSP phone image.

Bug: 125451157
Test: Verified output in out and dist folders

Additional verification:
- Without the VENDOR_BLOBS_NOTICE build fails
- Output shell artifact displays license as expected
- Shell artifact permissions are correct (ug executable)
- Shell artifact unzips inner zip after license agreement
- Unzipping shell artifact only unzips license.txt file
