Build arch-specific APKs on F-Droid

[momobobe]

Is your feature request related to a problem? Please describe. The APKs of F-Droid build are always big (now still over 100 MB), which waste much network traffic and storage

Describe the solution you'd like Setup builds for each architecture on F-Droid, like the Element APKs releases on Github, i.e. one APK for only one arch of armeabi-v7a, arm64-v8a, x86, x86_64

Describe alternatives you've considered Not sure, maybe try removing some unused libs or other components, if any

Additional context You can check other apps on F-Droid like VLC, to see how it's done

I'll probably follow upstream when they do it. https://github.com/vector-im/element-android/issues/7589

Alright, that's fine
