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.

Summary:
The code to display HMR errors on the client was reading the `description` field from Metro payloads. Metro does not include `description` in the body of its error payloads -- only in its `body.errors[]` items. This commit changes RN's HMR code to show `body.message` (set consistently with https://github.com/facebook/metro/pull/124) instead of the non-existent `body.description`.
Open a test RN app, enable HMR, and then introduce a syntax error in an app source file. See that the redbox provides information about the syntax error instead of just saying "TransformError undefined".

Summary:
In several pervious diffs we have moved symbolication of JS stack traces
to the packeger. This lets us save a bunch of memory (~80MB) and CPU on device,
reduces dependency on JS after exception occured.
This diff cleans up a bunch of code that was used to do symbolication on client side.

Summary:Source maps are broken on Genymotion right now as they aren't being loaded from the correct URL. refer - https://github.com/facebook/react-native/issues/5338#issuecomment-188232402
**Test plan**
Build and install UIExplorer from master branch in genymotion and enable hot reload. When you change a file and save it, you'll see a Yellow box due to source map fetching failed, as per the referenced comment.
Doing the same for this branch doesn't produce any yellow boxes.

Summary:We recently refactor the packager to transform the module names into numeric IDs but we forgot to update the HMR call site. As a consequence, HMR doesn't work the first time a file is saved but the second one.
This is affecting master as of 3/20. If we don't land this before v0.23 is cut we'll have to cherry pick it. This rev does *not* need to be picked on v0.22.

Summary:Sourcemaps on HMR where a couple of line off. The problem is that since the `__accept` call doesn't go through the sourcemaps pipeline we need to make sure that call is a single-line one.
This was originally written in a single line but I incorrectly updated it on 436db67126. Would be great having test coverage for this.

Summary:In order to be able to Hot Load Redux stores and modules that export functions, we need to build infrastructure to bubble up the HMR updates similar to how webpack does: https://webpack.github.io/docs/hot-module-replacement-with-webpack.html.
In here we introduce the minimum of this infrastructure we need to make this work. The Packager server needs to send the inverse dependencies to the HMR runtime that runs on the client so that it can bubble up the patches if they cannot be self accepted by the module that was changed.
This diff relies on https://github.com/facebook/node-haste/pull/40/files which adds support for getting the inverse dependencies.

Summary:

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

We should further improve this on the future by showing the actual stacktrace instead of the `HMRClient` one. Also, we need to integrate this with the dev plugin that opens in the default editor the file/line the user clicks on.

Summary:

Implement all the necessary glue code for several diffs submitted before to get Hot Loading work end to end:
- Simplify `HMRClient`: we don't need to make it stateful allowing to enable and disable it because both when we enable and disable the interface we need to reload the bundle.
- On the native side we introduced a singleton to process the bundle URL. This new class might alter the url to include the `hot` attribute. I'm not 100% sure this is the best way to implement this but we cannot use `CTLSettings` for this as it's are not available on oss and I didn't want to contaminate `RCTBridge` with something specific to hot loading. Also, we could potentially use this processor for other things in the future. Please let me know if you don't like this approach or you have a better idea :).
- Use this processor to alter the default bundle URL and request a `hot` bundle when hot loading is enabled. Also make sure to enable the HMR interface when the client activates it on the dev menu.
- Add packager `hot` option.
- Include gaeron's `react-transform` on Facebook's JS transformer.
The current implementation couples a bit React Native to this feature because `react-transform-hmr` is required on `InitializeJavaScriptAppEngine`. Ideally, the packager should accept an additional list of requires and include them on the bundle among all their dependencies. Note this is not the same as the option `runBeforeMainModule` as that one only adds a require to the provided module but doesn't include all the dependencies that module amy have that the entry point doesn't. I'll address this in a follow up task to enable asap hot loading (9536142)
I had to remove 2 `.babelrc` files from `react-proxy` and `react-deep-force-update`. There's an internal task for fixing the underlaying issue to avoid doing this horrible hack (t9515889).
