[feature] reduce motion (#1485)

This PR adds a user preference to reduce motion. When enabled the app
will not animate the camera (and perhaps skip other animations in the
future). It's actual implementation is as an `animateSpeed` property, so
we can also use it to speed up or slow down our animations if that's
something we want to do!

### Change Type

- [x] `minor` — New Feature

### Test Plan

1. Turn on reduce motion
2. Use minimap / camera features to zoom in / out / etc

- [x] Unit Tests

### Release Notes

- [editor] Add `reduceMotion` user preference
- Add reduce motion option to preferences
