How to extend DLC support to more distribution stores

The general steps/tips are:

1. Identify if the store have DLC support and have appropriate API or SDK for managing on-demand downloads. You may check this sheet containing information about various distribution stores for reference (might be outdated).
2. Create a new class that implements backends/dlc/store.h. See backends/dlc/android/playstore.cpp as an example.
3. Set the dlcspath in appropriate backends.
4. Use #ifdef USE_DLC where applicable. Before building, make sure to enable DLC support by using --enable-dlc with ./configure.
5. Add new entry to packaging/export-platforms.json for how to prepare, package and/or upload DLC packages for this specific distribution platform. You can include the 3rd party SDK/scripts/tools or self-written scripts in packaging/scripts directory. It is possible that you might need to change the schema for export-platforms.json and adapt the packaging/package.py accordingly. For more detailed and reasoning, you may read this blog
