refact: merge example and test example apps (software-mansion#2225)

## Description

This PR intents to merge together the example and test-example apps
resulting in less configuration files.
TestsExample and FabricTestExample apps are removed so there's only
Example, FabricExample and TVOSExample app to take care of.

it is more convenient to use Example and FabricExample apps to run tests
as there is less configuration files to take care of, less building and
less metro restarting. Simply replace the returned component in
`apps/App.tsx` with the selected test and you're ready for testing. For
example replace `<Example/>` with `<Test.Test42/>`.

## Changes

- removed TestsExample and FabricTestExample apps
- allowed for source change in `apps/App.tsx` file to switch between
example and tests
