Add aconfig flag support for runtime_resource_overlay

This change adds the support that was added to android_app in
https://r.android.com/2854663 for runtime_resource_overlay modules.

Implementation details:
- Add flags_packages as dependencies of runtime_resouce_overlay modules
- Pass the collected aconfig intermediate cache files to the
  aconfigBuildActionOptions.

Test: m nothing --no-skip-soong-tests
