This may be controversial.
Right now, RelayPrefetcher is initialized [here](https://fburl.com/p01iunr1), after bridge is initialized. I want to create a FBRelayPrefetcherModule instance eagerly (diff 3 in stack), and then pass that into the bridge module registry. This way, native side gets to use RelayPrefetcher before bridge is init, and JS still accesses the same instance of FBRelayPrefetcherModule.
The only other option is drastically change bridge init, to allow passing in some eagerly initialized instances.

Summary:
Previously, we stored a pointer to ShadowNode inside NSAttributedString's attributes to make possible retrieving an EventEmitter associated with some text fragment.
That worked fine besides only one caveat: the internal implementation of NSAttributedString is quite strange and that causes a memory leak. Because of some reason, NSAttributedString does not release stored attributes after own destruction (maybe OS uses some kind of caching).
So, now, instead of storing a strong pointer to ShadowNode inside NSAttributedString, we store a weak pointer to EventEmitter. Storing a weak pointer is okay because a desired lifetime of EventEmitter is guaranteed by LocalData stored inside a View. Storing a weak EventEmitter instead of weak ShadowNode will also help us with migration to ShadowView (we cannot store ShadowView weakly because it's a stack allocated object).

Summary:
The whole mounting iOS infra now uses `ComponentHandle` instead of `std::string` as a reference to particular `ComponentView` implementation. All changes are pretty straightforward, we use a different thing/type to refer to the particular class; no changes in the logic besides a new `RCTComponentViewFactory` that serves the same role of classes registry as Objective-C runtime served previously.
That has several benefits:
* It should be slightly faster, mostly because we don't need to convert `char *` strings to `std::string` and then to `NSString *`.
* We don't need string-based component-name maps anymore (at least on this layer). We can call classes as we want and it will work because of classes are now explicit about which ShadowNodes they are compatible with.
* Most importantly, it's explicit now! That means that no runtime magic is involved anymore and we can rely on static linting tool now and not be afraid of improper code stripping/overoptimization.

Summary:
If text is truncated and an inline view appears after the truncation point, the user should not see the inline view. Instead, we have a bug such that the inline view is always visible at the end of the visible text.
This commit fixes this by marking the inline view as hidden if it appears after the truncation point.
This appears to be a regression. React Native used to have logic similar to what this commit is adding: 1e2a924ba6/Libraries/Text/RCTShadowText.m (L186-L192)
**Before fix**
Inline view (blue square) is visible even though it appears after the truncation point:
The full text being rendered was:
```
<Text numberOfLines={1}>
Lorem ipsum dolor sit amet, consectetur adipiscing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna
<View style={{width: 50, height: 50, backgroundColor: 'steelblue'}} />
</Text>
```
**After fix**
Inline view is properly truncated:
**Test Plan**
Tested that the inline view is hidden if it appears after the truncation point when `numberOfLines` is 1 and 2. Similarly, verified that the inline view is visible if it appears before the truncation point.
**Release Notes**

Apparently, if a gesture recognizer got 'reset', OS does not call `touchesCancelled:` method, so we have to do it manually.
To implement this we have to split `_dispatchTouches:eventType:` into two methods: the first converts Objective-C touches to C++ touches, the second consumes that. We have to do this because during reset we don't have a collection of UIKit touches.

Summary:
It works great on iOS, and mostly works on Android, and is now OTA'able as part of the screen config! Haven't done template view yet. One remaining issue:
Layout is borked on Android. I'm guessing the issue has to do with the timing of setting the constraints in `updateRootLayoutSpecs` and calling `mBinding.startSurface` which actually builds the shadow tree. If I try to call `updateRootLayoutSpecs` earlier, it just crashes immediately. Here's the layout it spits out, which clearly has -440 for the x of 420006, which is the RCTText component, causing it to get cut off on the left of the screen:
```
updateLayoutMountItem for reactTag: 420006 x: -440, y: -13, width: 931, height: 78
