Make the Android version work again with KDE Craft
Some noteworthy changes:
- Drop qt-android-cmake in favor of KDE Craft and KDE Extra CMake Modules
- Update breeze-icons and use new keyframe-* icons in stead of custom ones
- Make it easier to build Glaxnimate Mobile on non-Android
- Don't force build in Potrace on Android
NOTE: Draft, because there are some build failures after rebase that I need to fix
