Summary: In some rare race condition (usually involving network request handling vs bridge shutting down), there may be bad access to an RCTModuleData that may have been de-allocated. To prevent crashes, let's guard the access and return nil appropriately.

Summary:
`RCTSurfaceHostingProxyRootView` surfaces are still automatically started right after the initialization to match `RCTRootView` interface, but `RCTSurfaceHostingView` must be started explicitly now. Also fixed some internal stuff so start and register are clear and distinct.
Background / initial motivation:
One tricky bit - we render the template as part of init`ing the rootView, so we don't know what the surfaceId will be before hand to register the UITemplate. Two possible solutions:
1) Require start be called explicitly after initializing the rootView, and setup the context in between.
2) Do something like "setUITemplateConfigForNextSurface" before creating the rootView, and have some hook when the surfaceId is assigned that associates the surfaceId with that "next" UITemplate stuff before.
(1) seems a lot cleaner, but it requires ever user of rootView to explicitly call start on it - how do you feel about that? Seems like we could also use that start call to decide if the initial render should be synchronous or not? start vs. startSync?

Summary:
Fixes#22530
As described in the issue, the previous behavior for the `RCTFatal` macro was to truncate the `reason` on the resulting `NSException` to 75 characters. This would ensure the reason would fit on a single line, but resulted in issues debugging errors that occurred in the wild, as many crash logging tools (like Sentry) discard the `name` value of the exception and use the `reason` as their primary identifier. At 75 characters, useful information like the location of the error would usually be truncated.
- [x] This extends the truncation threshold to 175 characters, which should be short enough to prevent full-screen-takeover length errors, but long enough to provide useful context to the error.
- [x] This adds a `userInfo` value to the resulting `NSException`. It copies over the `userInfo` from the `NSError` passed to the macro, and adds an "untruncated message" value that contains the untruncated version of the `NSException`'s reason.
[iOS] [Changed] - RCTFatalExceptions now include more information in their reason and a userInfo.

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.
