Summary: For some reason the scroll events are sometimes generated with highly irregular spacing, some coming less than a millisecond apart. For interactions that must track scrolling exactly, this can cause them to glitch. With a scroll throttle of less than 17 ms, the intention is clear that the UI should be updated in sync with the scroll view so we shouldn't drop any events.

Summary:
ScrollView's scrollTo behavior on iOS was recently changed to limit the offset to the content size plus any content inset (see #23427). This departure from the old behavior created UI issues for anyone that is using the over-scroll ability for the purpose of positioning elements at specific coordinates on the screen. Examples include using this behavior to position TextInputs above the virtual keyboard programmatically when focused or moving drop down elements positioned near the bottom of the content toward the top of the screen when selected to show a larger absolutely positioned item list. Default behavior does not change and this is an "opt-in" type of prop to re-enable the old behavior.

Summary:
Xcode 10.2 forbids creating categories for swift class that uses `+load` method. In react-native categories like this are used to register swift classes as modules (macro `RCT_EXTERN_MODULE`) This PR changes it to use `__attribute__((constructor))` instead of objc `+load` method.
I introduced new macro for this purpose, `RCT_EXPORT_MODULE_NO_LOAD`, it expands in something like:
```
void RCTRegisterModule(Class);
+ (NSString *)moduleName {
return @"jsNameFoo";
}
__attribute__((constructor)) static void initialize_ObjcClassFoo{
RCTRegisterModule([ObjcClassFoo class]);
}
```
Functions marked with `__attribute__((constructor))` are run before main and after all `+load` methods, so it seems like correct thing to do.

Summary:
This change fixes https://github.com/facebook/react-native/issues/23645.
The issue is that the `YGMarker.cpp`, `YGValue.cpp`, `YGConfig.cpp` and `log.cpp` files are already included in the Yoga compilation unit, so including these files in React's compile sources too results in "duplicate symbols" errors when loading React Native with `-force_load` (which behaves slightly differently to `-ObjC` - according to a colleague, "ObjC will scan through each object file in each library and force linking of any object file that contains Objective C code, while force_load will link every object file in a particular staticlib (regardless of whether or not the object file contains Objective C code)").
These changes seemed to be introduced by a few commits:
- D13819111 -> 43601f1a17
- D13439602 -> b5c66a3fbe
- D14123390-> e8f95dc7a1
- D7530369 -> 95f625e151
Perhaps we need to check with the original authors/any C++ experts to confirm if this fix is correct - it compiles for me but I'm not sure what the original intention of these changes was.

Summary:
There's a very old issue with reload logic: invalidation and resetting up of the bridge could be racing. In this case, we hit a redbox when:
* Chrome debugger is enabled in previous app run, then we launch the app again
* The bridge starts, then immediately reloads itself to connect to Chrome
* On the 2nd setup, the logic to update the green loading bar, with the % indicator for loading off metro, failed to find the DevLoadingView module instance because the bridge is in the middle of invalidating
See https://github.com/facebook/react-native/issues/23235
To test:
Using react-native init from github, do the steps in https://github.com/facebook/react-native/issues/23235, no more redbox. Note that the loading indicator % won't be proper still, but at least it doesn't crash/redbox.

There is no reason to allocate views ahead of time on the main thread.
There is a chance that this view will not be mounted and we are not saving any time because it's a sequential process anyway (because we are doing it on the main thread). Moreover, the switching context can only slowdown JS execution.

It's a little more complex than I initially thought, due to things I don't 100% understand about UISlider as well as Fabric, so I've left a TODO note to fix this at some point. We should be aware that view recycling doesn't appear to be working the way I would expect currently though.

TurboModules depend on a getConstants method. Existing ObjectiveC modules do not have this method. Therefore, I moved the contents of `constantsToExport` to `getConstants` and then had `constantsToExports` call `getConstants`.

Since all NativeModules will eventually need to be migrated to the TurboModule system, I didn't restrict this to just the NativeModules in Marketplace.

Summary:
When using building React Native using the `.xcodeproj` (either via linked projects in Xcode, or precompiling React Native, which is what we do), you'll get a duplicate symbol error:
```
duplicate symbol __ZN8facebook5react10IInspectorD0Ev ...
```
And a few more.
This is because the `InspectorInterfaces.cpp` file is included in _both_ the `React` target _and_ the `jsinspector` target, and since the `jsinspector` target gets linked into the `React` target, this means the symbols from `InspectorInterfaces.cpp` end up in `libReact.a` twice.

This PR removes `InspectorInterfaces.cpp` from the `React` target, as I believe was the original intent.
Since this bug is in the `xcodeproj` it only affects builds that use that, so CocoaPods and Buck users are unaffected.

Summary:
Given two apps loaded side-by-side and when a `Keyboard` event is triggered, there is no way to ascertain which app triggered the keyboard event. This ambiguity can arise in slide over/split view scenarios.
This pull request exposes the `isLocalUserInfoKey` property of the native `UIKeyboard` iOS events to the `Keyboard` event listener; this property will return `true` for the app that triggered the keyboard event.
(Also, I threw in a couple of Keyboard.js tests just for fun 😅)
[iOS][Added] - Expose isLocalUserInfoKey to keyboard event notifications
1. Load two apps side-by-side, with the app on the left side subscribing to the keyboard events (and logging out the events as they happen)
1. Trigger a keyboard to appear with the left app. The logged keyboard event will contain the `isEventFromThisApp` property which will be true.
1. Dismiss the keyboard
1. Trigger a keyboard to appear with the right app. The left app will still log the keyboard event, but the event's `isEventFromThisApp` property will be false (because the left app didn't trigger the keyboard event)
