Rubén Norte 333755367f Declare some missing globals
Summary:
This declares a few globals that were missing in our `global.js` Flow declaration file:
* `process`
* `performance` with its current definition. We'll replace it with the new API when we replace `setupPerformance` with `setupWebPerformance`.
* `navigator`
* `setImmediate`
* `clearImmediate`

Eventually we should stop including all DOM definitions that Flow provides out of the box and define only what we provide (which is pretty much this file).

Changelog: [Internal]
