Summary: Added `snapToStart` and `snapToEnd` props to ScrollView which work together with `snapToOffsets` and determine whether the beginning and end of the list automatically count as snap offsets or not. If not, the list is allowed to free-scroll between its start/end and the first/last snap offset.

Summary:
To be able to test out new approach for NativeModules, introduce a simple runtime flag to enable the new system (doesn't exist yet). In addition, each module should declare a static `+ (BOOL)allowJSIBinding` in the objc class to be considered for the new approach. Doing so skips the processing of the module during bridge startup.
Note: this doesn't do anything special for `- (NSArray *)extraModulesForBridge:(RCTBridge *)bridge` impl yet.

Summary:
Currently `SafeAreaView` works only on iOS 11, because implemented in terms of native safeArea API, that not exists in older iOS versions. But this make it hard to use the component in real applications, because content will be under top bars on older versions of iOS and no reliable way to workaround this in js. More motivation in #17638
This changeset emulate safe area in terms of `UIViewController` layout guides API if safeArea not available.
Fixes#17638, #18255
I run RNTester with these simulators: iPhone6 (9.3), iPhone6 (10.0), iPhone6 (11.2), iPhoneX (11.2)
- Start RNTester application
- Look on top header, it should not overlap status bar
- Go to the `<SafeAreaView>` example, open modal
- Modal area should not overlap status bar

This seemed like the simplest way to do this to register in the existing

NOTE: The new version of this fixes the problems with dylibs, but not the -ObjC flag removal. This seems like the right call to avoid users having to implement c-functions to return their classes; instead we used objc_getClass.

1. Weakly link the `WebKit` framework in the `ReactInternal` library, so that the compiler doesn't die when it encounters a WebKit symbol.
2. Undo dynamic linking of WebKit in Catalyst.
3. Undo dynamic linking of WebKit in AdsManager
4. Before the first `WKWebView` is instantiated, dynamically load the `WebKit` framework.

This diff implements background colors for the `RCTWKWebView` component by proxying the background color prop to the underlying `WKWebView` and its underlying `UIScrollView`.
There's few differences between `backgroundColor` in `RCTWebView` and `RCTWKWebView` implementations:
1. With `UIWebView,` the background color gets applied after the page loads. With `WKWebView`, this isn't necessarily true. This results in a white flicker on solid backgrounds because sometimes, the background color is set before the page loads. This video illustrates the problem: https://our.intern.facebook.com/intern/px/p/9QBH
1. As far as I can tell, `WKWebView` doesn't handle transparent backgrounds correctly. Either that, or I could be setting the background color incorrectly. I set the background color to `rgba(1, 1, 1, 0.5)` and recorded how both `RCTWebView` and `RCTWKWebView` render. These two videos indicate the differences:
**RCTWebView: Lighter background**
https://pxl.cl/9R13
**RCTWKWebView: Darker background**
https://pxl.cl/9R1b
I tried to replicate this on the web. According to [[ https://our.intern.facebook.com/intern/fiddle/zCHu/ | this fiddle ]], `RCTWebView` is correct. Clearly, RCTWKWebView is rendering transparent backgrounds a bit darker than necessary. This doesn't seem simple to debug, so I've created a task to document this work: T23815343. I'll get to it eventually.

For example, when the text `apple.com` is detected, if the `link` data detector type is enabled, the web view will actually render a link that takes the user to the Apple home page.
In this diff, I implement the `dataDetectorTypes` prop. The data detector types supported are:
1. phoneNumber
1. link

The content that renders within the `WKWebView` instance actually renders inside a `UIScrollView`. On that scroll view, we can adjust the `decelerationRate`, which controls how fast the view stops scrolling after the user lets go while scrolling.
In this diff, I implemented the `decelerationRate` prop for `WKWebView`, which gets forwarded to the `UIScrollView` instance underlying the web view.
**Note:** Even though we accept a floating point value for the deceleration rate, the native `UIScrollView` component only allows two inputs:
1. `UIScrollViewDecelerationRateNormal`: 0.998
2. `UIScrollViewDecelerationRateFast`: 0.99

This diff implements message passing between the `WKWebView` and React Native. As with `<WebView/>`, we can only send/receive strings.
**Usage:**
1. Set `messagingEnabled` to `true`.
1. To send data from the web view to React Native, call `postMessage(data)` within the web view. This forces React Native to execute the `onMessage` prop on the `WKWebView` component. `onMessage` will be called with an event `e`, where `e.nativeEvent.data` will be the data you passed into `postMessage`.
1. To send data from React Native to the web view, call `UIManager.dispatchViewManagerCommand` to dispatch the `UIManager.RCTWKWebView.Commands.postMessage` command. Look at [[ https://fburl.com/u1wusf2f | this part of the existing `<WebView/>` ]] component for more details. After you make the call, React Native will dispatch a `'message'` event to the `document` object within the webview. You can listen to the event by doing `document.addEventListener('message', callback)`. Let the event dispatched be `e`. Then, `e.data` is the data you sent over from React Native.

The accessibilityHint provides some more information about an element

The accessibilityHint is a core accessibility property on iOS.
From https://developer.apple.com/documentation/objectivec/nsobject/1615093-accessibilityhint:
> An accessibility hint helps users understand what will happen when they perform an action on the accessibility element when that result is not obvious from the accessibility label.
Related issue: https://github.com/facebook/react-native/issues/14706
The npm scripts `test`, `flow`, `lint` and `prettier` are satisfied.
I added a couple of examples to the RNTester app. The Accessibility Inspector on Mac helps debugging accessibility stuff on a simulator, but it does not show the accessibilityHint. Therefore I tested the RNTester app on an iPhone 8 device using VoiceOver to verify the hint functionality. It works fine, and I've tested disabling and enabling "read hints" in the VoiceOver settings on the phone.

Summary:
Context:
After discussing with yungsters, `currentViewStates` is a very ambiguous name for a prop, especially because there are only two possible values. From a developer's perspective, it makes more sense to just call them `accessibilityStates` because the main use for them is to add states to Talkback and Voiceover.
Also, the actual implementation of what we're changing under the hood in Native Code is abstracted away from developers using React Native, so as long as behavior is as they would expect, it makes more sense to change the name into a clear one.
Changes in this Diff:
Renamed the view property exposed to native iOS code from `currentViewStates` to `accessibilityStates`
Also deleted setting the userInteractionEnabled view property, because we want to keep it as just an accessibility property.

This diff consists of many interdependent changes which support one simple idea: YogaLayoutableShadowNode is now using YGNode children to iterate on them (it previously relied on `ShadowNode::getChildren()`). All other changes are just an unavoidable consequence of that. Hence we don't need to filter child nodes every single time when we do layout anymore! The logic around `clone callback` is also drastically simpler now.
The new approach also implies that `LayoutableShadowNode` and `YogaLayoutableShadowNode` don't use `shared_ptr`s to refer to ShadowNode objects because new relationship does not imply ownership. No more `SharedShadowNode` objects in those two classes.

If disabled is passed in, userInteractionEnabled of the view will be set to false.
The value that is passed into currentviewStates is converted to a UIAccessibilityTrait Enum and masked in with existing UIAccessibilityTraits on that native view.
