Summary:
While testing 0.65, we noticed issues with hermes on iOS in the template projects
These changes create a subspec to the react-core pod so that it can access hermes header correctly.

Summary:
FlatList relies heavily on onScroll events + the measure API. In Fabric, usage of `measure` relies on C++ having an accurate view of the current scroll position of the ScrollView.
We already have a mechanism for updating the scroll position in C++ using UpdateState. But, it is only used currently at the /beginning/ and /end/ of scrolling, and UpdateState is not called /during/ scrolling at all.
This means that we will see a series of events like this while scrolling:
```
Scrolling begins
UPDATE C++ STATE: scrollLeft = 0, scrollTop = 0
JS event: onScroll x=0, y=0
JS event: onScroll x=0, y=100
JS event: onScroll x=0, y=200
...
JS event: onScroll x=0, y=1000
UPDATE C++ STATE: scrollLeft = 0, scrollTop = 1000
```
Notably, not many C++ state updates are queued; and the last one is queued AFTER the JS event is sent. The last JS event and UpdateState will race, which means that sometimes the C++ update will /lose/ and C++ will have an inaccurate view of the world when FlatList receives the onScroll event and calls `measure`.
My proposed solution, gated behind a feature flag, is to delay /some/ onScroll events until the C++ UpdateState has made its way back to Java, and send UpdateStates more frequently. The balance here is that UpdateState is a relatively expensive operation, so we probably still want to call it /less/ than we call onScroll. This means that `measure` will still return some incorrect results but will return correct results more frequently. Win?

Changelog:
[iOS][Added] - Description
When compiling iOS apps with flag `-Wnullability-completeness` (like Lightspeed app and soon Instagram), Objective-C headers are required to either have full *explicit* nullability annotations on all members of its public API, or none at all; partially annotated headers will fail to build that module.
RN native modules are currently generated with *partial* annotations. This works today because most apps are not compiled with `-Wnullability-completeness` turned on. But when we flip the switch for Instagram, the app doesn't build due to importing these RN partially annotated modules.
JavsScript Flow types are implied nonnull, and the current RN codegen translates Flow's [maybe/optional](https://flow.org/en/docs/types/maybe/) type to Obj-C `_Nullable` annotation, and everything else without an explicit Obj-C annotation. However this creates a mismatch with the Obj-C type system, where the implied default is *unannotated*, which is handled differently from nonnull when built with the nullability compiler flags.
There is a simple Obj-C macro that automatically adds *explicit nonnull* annotations to all members in a header: `NS_ASSUME_NONNULL_BEGIN` / `NS_ASSUME_NONNULL_END`. If we add this to *all* RN-generated headers, however, we run into issues:
1) We may erroneously assume any previously-unannotated header was meant to be nonnull and cause future bugs
2) Another compiler flag (`-Wnullable-to-nonnull-conversion`) statically analyzes Obj-C implementation code to prevent us from ever passing null to one of these headers. Much existing Obj-C code will break here, and it's ambiguous if these are true or false positives because of the first point.
Instead, in this diff we add a new BUCK flag `ios_assume_nonnull` to let module authors opt into automatic nonnull for unannotated members so that Obj-C headers are generated correctly in alignment with Flow's type system. We can migrate all libraries individually as needed and eventually make this the RN native codegen default.

Add unit tests for Layout Animations.
This first batch generates a random mutation, then animates it to completion.
I found one issue with UPDATE+REMOVE+INSERT animation consistency. That shouldn't cause any crashes in production, but is a chance to improve consistency of mutations overall - and could in theory point to memory corruption, though it's somewhat unlikely.
I ran with randomized seeds, found issues, fixed them, re-ran to ensure issues were fixed, rinsed and repeated. At the end I was able to run dozens of times (with random seeds) and found nothing.
The next step is to repeatedly generate mutations that conflict with ongoing animations.
