Summary:
If the z-index was updated after the initial mount, changes would not be reflected because we did not recalculate the z-index mapped child views and redraw the view. This adds code to do that and call it whenever we update z-index.
**Test plan**
Tested by reproducing the bug with 2 overlapping views that change z-index every second. Made sure it now works properly and z-index changes are reflected.

Summary:
This is the better fix for the same issue as mentioned in PR https://github.com/facebook/react-native/pull/14560
Certain rotateX, rotateY, scaleX and scaleY animations do not work correctly on some phones in Android 7.0.0, causing issues such as https://github.com/facebook/react-native/issues/14462 and https://github.com/facebook/react-native/issues/13522.
The issue can be fixed on JS side by setting an additional transform for perspective, eg. `{perspective: 1}` which triggers a `setCameraDistance` call in native code.
The fix in this PR always sets the camera distance on transforms, even when no perspective transform was specified. The default camera distance is set before the scale multiplication, to make sure that the value is appropriate for the phones density. The value calculates to an Android 'default' camera distance of 1280 * scale multiplier; https://developer.android.com/reference/android/view/View.html#setCameraDistance(float)
If a perspective transform is specified, this value will be used correctly still.
This fix was tested on the RNTester. Before the fix, on some devices, the FlatList example, with inverted turned on, will not display the list.
Devices that have been confirmed to have this issue:
FRD-AL10(honor 8) EMUI:5.0 android: 7.0
MHA-AL00(Mate9) EMUI:5.0 android:7.0
Huawei P10 VTR-L09, running Android 7.0
After the fix, the inverted FlatList displays correctly.

Summary:
This PR fixes an issue with rotation decomposition matrix on android.
The issue can be illustrated with this sample code https://snack.expo.io/r1SHEJpVb
It surfaces when we have non-zero rotation in Y or X axis and when rotation Z is greater than 90deg or less than -90deg. In that case the decomposition code doesn't give a valid output and as a result the view gets rotated by 180deg in Z axis.
You may want to run the code linked above on android and iOS to see the difference. Basically the example app renders first image rotated only by 89deg and the next one by 91deg. As a result you should see the second view being pivoted just slightly more than the first image. Apparently on android the second image is completely flipped:
iOS:

Android:

The bug seemed to be caused by the code that decomposes the matrix into axis angles. It seems like that whole code has been overly complicated and we've been converting matrix first into quaternion just to extract angles. Whereas it is sufficient to extract angles directly from rotation matrix as described here: http://nghiaho.com/?page_id=846
This formula produces way simpler code and also gives correct result in the aforementioned case, so I decided not to debug quaternion code any further.
sidenote: New formula's y angle output range is now -90 to 90deg hence changes in tests.

Summary:
Use `getChildDrawingOrder` instead of reordering views. The old implementation didn't work properly when `removeClippedSubviews` was enabled and this one should have better performance since we don't play with the view hierarchy at all.
This fixes weird bugs with sticky headers in `SectionList` and allows removing the hack that disabled `removeClippedSubviews` when using sticky section headers.
**Test plan**
Tested using the SectionList and ListViewPaging examples that use sticky headers which uses z-index.

Summary:
The app crashes because of `TouchEventCoalescingKeyHelper.getCoalescingKey` throwing an exception when move on the edge of some phones like HUAWEI P9. It's caused by that the down time differs from `ACTION_DOWN` to `ACTION_MOVE` which belongs to the same gesture when I touched on the edge of my HUAWEI P9. It seems a native bug of manufacturer. Related issue #11302.

Summary:
See https://github.com/facebook/react-native/issues/10845
onSizeChanged is enqueueing a runnable from the ui thread that references a shadow view by id on the native modules thread. Since the shadow thread 'runs ahead' of the UI thread (e.g. it has a newer state of the world than the UI thread), this isn't safe. By the time that code block runs, it's possible that an update from JS has already removed that view from the shadow hierarchy (a change which would then propagate to the native hierarchy on the UI thread).

I don't remember exactly where we talked about this but LayoutAnimation on Android is pretty stable now so there's no reason to keep it behind an experimental flag anymore.

Summary:
This diff adds display:none support to React Native. This enables hiding components which still calling their render method and keeping them within the state of your application. This enables preserving state in a component even though the component is not visible. Previously this was often implemented by rendering a component off screen as a work around. See below playground for usage.
```
class Playground extends React.Component {
render() {
return (
<View style={{width: '100%', height: '100%', flexDirection: 'row', backgroundColor: 'white'}}>
<View style={{width: 100, height: 100, display: 'none', backgroundColor: 'red'}}/>
<View style={{width: 100, height: 100, backgroundColor: 'blue'}}/>
</View>
);
