[flow] Upgrade from 0.279 -> 0.280

Flow 0.280 introduced stricter type checking for `incompatible-type` errors,
requiring additional $FlowFixMe suppressions alongside existing ones. Changes:

- Made `QueuingStrategy` properties optional in streams.js
- Made all properties optional in Web Animations API types (EffectTiming,
  KeyframeAnimationOptions, etc.)
- Added `$FlowFixMe[incompatible-type]` alongside existing suppressions in
  multiple files where Flow now reports additional type mismatches
