Use Lolex to implement Jest fake timers

[SimenB]

Summary

This is an alternative to #5171, that's the exact same except for the last commit, which makes sure to just mock the APIs that Jest is currently mocking, which are these: https://github.com/facebook/jest/blob/fb61bfffb803bad0c2ff9ab1798a6c4c31cb14fa/packages/jest-util/src/FakeTimers.js#L104-L113.

Hopefully, this can be merged and applied at FB, and then we can merge #5171 which will mock the rest of the timers (Date, requestAnimationFrame, performance.now etc.).

This is not meant to replace #5171.
