Publish update info via SystemUpdateManager
When 16K OTA is applied, this info would need to be published
to a SystemUpdateManager so that we don't clobber the updates with
other pending updates. Similarly, Fetch the pending update info from
SystemUpdateManager before applying update.
Test: m Settings && adb install -r $ANDROID_PRODUCT_OUT/system_ext/priv-app/Settings/Settings.apk
