Amend the apex info for ota package
We have already logged the compressed apexes in the target-files.
Because we want to support the apex metrics during OTA update, also
include the uncompressed apexes in the META/apex_info.pb.
For incremental OTA packages, include the source apex version for
each apex package as well.
