AAPT2: Update versionCode in multi-APKs.

Set versionCode in the AndroidManifest.xml so each artifact has a unique
version code. This will allow the play store to serve up the correct
APKs.

The versionCode is determined by taking the versionCode from the input
APK and adding the configured version to that. If an artifact does not
have a version, the next version is used based on the order in the
configuration file. If the firs artifact does not have a version, it
starts at 1, so that all artifacts have a different version code to the
base APK.

Bug: 64972562

Test: unit tests
Test: manually optimized an APK into multiple APKs and confirmed versions:
  aapt dump badging ${apk} | grep versionCode
