Add support for 8.5.3

- Support for new channel type (news) is added
- New color: primary_660, not used anywhere
- `switch_thumb_normal_material_light` is no longer top bar color, this will affect customtheme's top bar, I'll fix it when I find time.
- crashlytics was updated (ahhhhhhhhhhhh)
- fabric was updated (ahhhhhhhhhh)
- drainEventsQueue from analytics was rewritten (ahhhhhhhhhhhhhhhhh)
