Recompile packages with cdex in vdex'es in background dexopt when the

disable cdex experiment is enabled.

Test: adb install out/dist/com.google.android.art.apex
      adb reboot && adb wait-for-device
      m AppUsedByOtherApp
      adb install-multiple out/target/product/vsoc_x86_64/testcases/AppUsedByOtherApp/x86_64/AppUsedByOtherApp.apk AppUsedByOtherApp.dm
      # where AppUsedByOtherApp.dm is created from a non-empty profile
      adb root && adb wait-for-device
      adb shell pm bg-dexopt-job
      adb shell find data/app data/dalvik-cache -name \*.vdex \
        \| xargs grep cdex001
      # -> matches are found, e.g. in system apps
      adb shell pm compile -f -m speed-profile \
        android.compilation.cts.appusedbyotherapp
      adb shell grep cdex001 \
        /data/app/\*/android.compilation.cts.appusedbyotherapp-\*/oat/x86_64/base.vdex
      # -> check that a match is found
      adb shell setprop \
        persist.device_config.runtime_native_boot.disable_compact_dex \
        true
      adb shell pm bg-dexopt-job
      adb shell find data/app data/dalvik-cache -name \*.vdex \
        \| xargs grep cdex001
      # -> check that no matches are found
