Rubén Norte d5e9e55fa3 Remove @providesModule from all modules
Summary:
This PR removes the need for having the `providesModule` tags in all the modules in the repository.

It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)

* Checked the Flow configuration by running flow on the project root (no errors):

```
yarn flow
```

* Checked the Jest configuration by running the tests with a clean cache:

```
yarn jest --clearCache && yarn test
```

* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:

```
yarn run start --reset-cache
curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android'
curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios'
```

[INTERNAL] [FEATURE] [All] - Removed providesModule from all modules and configured tools.
Closes https://github.com/facebook/react-native/pull/18995
