Summary: This diff makes plugin loading async, which we'd need in a browser env (either because we'd use `import()` or we need to fetch the source and than eval it), and deals with all the fallout of that

Summary:
This diff moves RenderHost initialisation to jest, which is thereby treated as just another 'Host' like flipper-ui, the electron app etc. A benefit is that it provides a mocked flipperServer by default that can be used to mock or intercept requests. See LaunchEmulator.spec as example.
Also made the jest setup scripts strongly typed by converting them to TS.
This change allows the test stub configuration, which was OS dependent, out of flipper-ui-core.
