Summary: When bundling a production bundle of flipper-ui / flipper-server, noticed that a lot of irrelevant stuff ends up. Like: `jest`, `metro`, `testing-library`. The whole jungle basically. Will add safety checks in the next diffs that this no longer happens

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.
