Summary:
By default, the text color is `#000000` on iOS and different on Android, e.g. `#808080`, depending on the manufactorer.
This PR changes it so that newly created projects all have the text color `#000000` by default on both iOS and Android.
The argument for this is to make the app by default be more consistent between platforms.
Expo also does this: https://github.com/expo/expo/blob/master/android/expoview/src/main/res/values/styles.xml#L31

Summary:
By default, an alert is `cancelable` on Android but not on iOS.
This PR changes the behavior so that the Alert is not dismissable on Android by default.
The motivation is that many developers develop on iOS and test on Android, and do forget to consider the case that the alert is dismissable.
Consistent behavior by default makes it easier to develop cross-platform apps in general.

Summary:
If an app [builds from RN source](https://facebook.github.io/react-native/docs/building-from-source), there was an error for jsc-android not found.
It is a side effect of my previous [JSC as node dependency change](8e375850de)
For building from RN source case, the jsc-android is located at `/path/to/app/node_modules/jsc-android`.
Original gradle task will try to find it at `/path/to/app/node_modules/react-native/ReactAndroid/../node_modules/jsc-android`, as ReactAndroid project path was being override inside node_modules.
The change fixes the building from source case.

ShadowTree commits happen concurrently with limited synchronization that only ensures the correctness of the commit from ShadowTree perspective.
At the same time artifacts of the commit () needs to be delivered (also concurrently) to the proper thread and executed in order (not-concurrently). To achieve this we need some synchronization mechanism on the receiving (mounting) side. This class implements this process.
Practically, this diff fixes a problem with glitching UI during the very first render of Fabric screen.

Summary:
Registries, providers, providers of registries, registres of providers. All that can be really confusing, but that represents best the constraints and desires that we have:
* We need to be able to register components on-the-fly (so we need a mechanism that will propagate changes);
* We don't want to register ComponentDescriptors separately from ComponentView classes;
* C++ not always gives us abstractions that we want (e.g. pointers to constructors).
After the change, we can remove the whole Buck target that has a bunch of handwritten boilerplate code.
There is a still room for polish and removing some concepts, types or classes but this diff is already huge.

Summary:
ComponentDescriptorProvider represents unified way to create a particular descriptor.
Now all ComponentViews (which support RCTComponentViewProtocol) expose a `ComponentDescriptorProvider` which will allow creating and registering ComponentDescriptor instances for all visual components automatically as a part of ComponentView registration process.
Don't panic, everything is still being as explicit as it always was, no magic involved; we just will have only one registration step instead of two parallel.
That also opens a way to register components on the fly.

On the left we have metro, on the right is the xcode console with some logging to show the reconnecting phase. When we kill the metro server you can see the app tries to reconnect once and that's it - when metro is started back up, you can see the notification that there are no apps running and can also see that cmd+opt+r doesn't work anymore
I updated the logic to optimistically start the connection and if it's still unavailable to retry again after the timeout

Summary:
React Native has a `NativeModule` to manipulate programmatically the dev menu options (live reload, hot reload, remote debugging, etc), called [`DevSettings`](https://github.com/facebook/react-native/blob/master/React/Modules/RCTDevSettings.mm#L120). However this module is only available for iOS.
This PR brings the same `DevSettings` for Android, making it a cross-platform NativeModule.
Motivation: Right now if your app needs to programmatically reload RN, one option is to install [`react-native-restart`](https://www.npmjs.com/package/react-native-restart). It's a tiny dependency, but it's annoying to have to install it, while the code to do so is inside RN codebase. According to NPM, react-native-restart has ~12k weekly downloads, shows it's a recurring feature for many apps (my case).
Thus making `NativeModules.DevSettings` is a small increment in the codebase, just exposing the dev menu methods, to improve the Development Experience
[Android] [Added] - Add DevSetting native module (making it cross-platform)
With expection of `setIsShakeToShowDevMenuEnabled`, the following methods will be available for both platforms:
* reload
* setHotLoadingEnabled
* setIsDebuggingRemotely
* setIsShakeToShowDevMenuEnabled
* setLiveReloadEnabled
* setProfilingEnabled
* toggleElementInspector

It includes (amongst other things) the following fixes, as described on the [12.1.4 release page](https://github.com/wix/Detox/releases/tag/12.1.4):
- hotfix: redundant logs in the folder
- fix: stabilize simulator log recording
It also updates the detox test script and config in `packages.json` (which was previously missed when detox was updated to 12.1.x). It will remove the following deprecation warnings:
```

detox[6416] WARN: [test.js] Please edit your package.json according to the migration guide: https://wix.to/I0DOAK0

Instead of extra preprocessing the test folder by `detox`, it will now be passed straight to `jest`.

Summary:
If you call into a Java method (from C++ using JNI) that raises an exception, the JNI call won't actually raise a C++ error. Instead, the `JNIEnv` will record the pending Java exception and the C++ will continue executing as normal. This is bad because the next time you call into JNI, the app will actually crash, unless you explicitly cleared the exception using `JNIEnv::ExceptionClear()` before the JNI call.
With respect to TurboModules, we need to make sure that RedBoxes show up whenever a native methods raise an exception. We also don't want the app to crash when a JNI method call fails because of a raised exception. Therefore, in this diff, I raise a C++ exception if `JNIEnv::ExceptionCheck()` is true.

Summary:
Would like feedback from the community as this may not be the best solution for all
I would like to restrict (or paginate) the fling of a horizontal ScrollView when `snapToInterval` is set. This is not currently possible with `pagingEnabled`, since the pagination works only when items are the entire width of the ScrollView.
This implementation simply restricts the predicted `targetOffset` found from the `x` velocity and replaces it with the offset when the pan gesture ended.
To get pagination working, I may paginate based on the interval by calculating the offset delta from the beginning of the gesture to current offset and restricting the scrolling behavior to the `snapToInterval`. If this is preferred, I can update this PR or make a new one, but wanted to start a discussion since it seems like there are many in the community that would like this feature #21302 .
[General] [Added] - add prop `disableIntervalMomentum` to disable the predictive scrolling behavior of horizontal ScrollViews
