Summary:
This fixes issues #18954 and #15497
The transformation from Set to (an reversed) Array does not work on Android devices when the remote debugging was started with `react-native run-android`.
<!--
Required: Write your motivation here.
If this PR fixes an issue, type "Fixes #issueNumber" to automatically close the issue when the PR is merged.
-->
Add the following code to your App.js and run the app with `react-native run-android` in an Android device:
```
componentDidMount() {
BackHandler.addEventListener('hardwareBackPress', () => {
console.warn('Callback called. Do not close app. Do nothing at all.');
return true; // Do not close the app.
});
}
```
After adding this, the app should NOT close when you press the back button. Without this fix, the app closes (which is the default behaviour).
See also the comments from Victoriayangx in #18954 and #15497.

Publishing as a minor version, since there are no breaking changes. This way, this will also be available already in RN 0.57, since it depends on Metro 0.57 (https://fburl.com/t2j2k2sw).

Summary:
D8842691 split AccessibilityTraits into multiple RN properties. However, the accessor code did not support REMOVING traits.
This results in buttons that were disabled (AccessibilityTraits & NotEnabled === true) never being enabled.
Fix the issue by making the split accessors properly mask in the bits, allowing you unset them without disturbing bits managed by the other accessor.
NOTE: setting AccessibilityTraits and AccessibilityRole or AccessibilityStates will still result in bugs.

Summary:
**Motivation**
Whenever a user changes the system font size to its maximum allowable setting, React Native apps that allow font scaling can become unusable because the text gets too big. Experimenting with a native app like iMessage on iOS, the font size used for non-body text (e.g. header, navigational elements) is capped while the body text (e.g. text in the message bubbles) is allowed to grow.
This PR introduces a new prop on `<Text>` and `<TextInput>` called `maxFontSizeMultiplier`. This enables devs to set the maximum allowed text scale factor on a Text/TextInput. The default is 0 which means no limit.
Another PR will add this feature to Android.
**Test Plan**
I created a test app which utilizes all categories of values of `maxFontSizeMultiplier`:
- `undefined`: inherit from parent
- `0`: no limit
- `1`, `1.2`: fixed limits
I tried this with `Text`, `TextInput` with `value`, and `TextInput` with children. For `Text`, I also verified that nesting works properly (if a child `Text` doesn't specify `maxFontSizeMultiplier`, it inherits it from its parent).
Lastly, we've been using a version of this in Skype for several months.
**Release Notes**
[GENERAL] [ENHANCEMENT] [Text/TextInput] - Added maxFontSizeMultiplier prop to prevent some text from getting unusably large as user increases OS's font scale setting (iOS)

Summary:
Currently `ReactModuleSpecProcessor` looks at each of the modules, and sees if the module inherits from `CxxModuleWrapper` to see if it is a C++ module or not. With this change, we now require C++ modules to explicitly specify that they are C++ modules, instead of doing annotation processing magic.
Also note that annotation processor do not work with interfaces but with classes only, so this also removes the dependency of the annotation processor from the bridge buck target.

Summary:
Use a whitelist to validate user-provided file names. This doesn't cover the entire range of valid filenames but should cover almost all of them in practice. Allows letters, numbers, periods, dashes, and underscores. Opting to use a whitelist instead of a blacklist because getting this wrong leaves us vulnerable to a RCE attack.

Voalá, this small change actually implements view flattening. Obviously, it does not work right now because there are no `ShadowNode` classes which implement `isLayoutOnly`.

Summary:
@public
This is quite a big diff but the actual meaningful change is simple: now we use ShadowView class instead of ShadowNode in mutation instructions.
Note:
* In some places (especially during diffing) we have to operate with ShadowNodeViewPair objects (which represents a pair of ShadowNode and ShadowView). The reason for that is that we cannot construct child ShadowViews from parent ShadowViews because they don't have any information about children.
* `ShadowTree::emitLayoutEvents` is now much simpler because ShadowView better represents the specifics of this kind of object.
* The code in RCTMountingManager also became simpler.
This change will allow us to implement more cool tricks soon.

Summary:
@public
We need some another object like ShadowNode (but not ShadowNode) to represent an instance of the component in the mutation instructions. This is
the main motivation for introducing ShadowView.
Why not use ShadowNode? ShadowNode is designed to represent a node in ShadowTree, not be a part of a mutation instruction.
* ShadowNode exposes some APIs that should not be exposed to the mounting layer;
* ShadowNode is an immutable data structure, so we cannot mutate it in some way which can be meaningful for mounting;
* We should not add to ShadowNode any functionality which is needed only for mounting;
* ShadowNode is a bit more heavy object to share that it needs to be; it's exposed (embedded into Mutation) as a `shared_ptr` which is not optimal from the performance perspective;
* Retaining ShadowNode from mounting code can unnecessarily extend its lifetime which can negatively affect memory usage.

Summary:
This pull request adds the ability for a platform developer to provide a `"haste"` key under the `"rnpm"` key in their `package.json` which allows the packager to pick up that platform's javascript files. The intent is to remove the need to have custom platforms hardcoded in. This is inspired by the `"jest": { "haste": {} }` key used by jest.
For example, React Native Dom would have an entry like:
```json
{
"rnpm": {
"haste": {
"providesModuleNodeModules": [
"react-native-dom"
],
"platforms": [
"dom"
]
}
}
}
```
Support for more keys (path blacklists perhaps?) could be added in the future.
