Skip dexopt if app has preferCodeIntegrity=true

Test: 1. adb install com.android.cts.appintegrity.apk
      2. adb shell cmd package compile -m speed -f com.android.cts.appintegrity
      3. adb shell oatdump --oat-file=$(echo /data/app/com.android.cts.appintegrity-*/oat/arm64/base.odex)
      => no code is observed in oatdump, only if preferCodeIntegrity=true
