Rob Hogan 09a910f80b Prepare for Jest 27+ by making legacy fake timer use explicit
Summary:
Jest 27 [flips defaults](https://jestjs.io/blog/2021/05/25/jest-27#flipping-defaults), making "modern" fake timers (ie, `sinonjs/fake-timers`) the default, over "legacy", which we currently use.

We're not quite ready for modern timers yet, partly due to Promise polyfills (https://github.com/facebook/react-native/pull/34659), and also some internal issues with specific tests.

This makes our use of legacy timers explicit in preparation for an update to Jest. A switch to modern timers may follow later.
