Summary:
JSCallInvoker requires a `std::weak_ptr<Instance>` to create. In our C++, `CatalystInstance` is responsible for creating this `Instance` object. This `CatalystInstance` C++ initialization is separate from the `TurboModuleManager` C++ initialization. Therefore, in this diff, I made `CatalystInstance` responsible for creating the `JSCallInvoker`. It then exposes the `JSCallInvoker` using a hybrid class called `JSCallInvokerHolder`, which contains a `std::shared_ptr<JSCallInvoker>` member variable. Using `CatalystInstance.getJSCallInvokerHolder()` in TurboModuleManager.java, we get a handle to this hybrid container. Then, we pass it this hybrid object to `TurboModuleManager::initHybrid`, which retrieves the `std::shared_ptr<JSCallInvoker>` from the `JavaJSCallInvokerHandler`.
There were a few cyclic dependencies, so I had to break down the buck targets:
- `CatalystInstanceImpl.java` depends on `JSCallInvokerHolderImpl.java`, and `TurboModuleManager.java` depends on classes that are packaged with `CatalystInstanceImpl.java`. So, I had to put `JSCallInvokerHolderImpl.java` in its own buck target.
- `CatalystInstance.cpp` depends on `JavaJSCallInvokerHolder.cpp`, and `TurboModuleManager.cpp` depends on classes that are build with `CatalystInstance.cpp`. So, I had to put `JavaJSCallInvokerHolder.cpp` in its own buck target. To make things simpler, I also moved `JSCallInvoker.{cpp,h}` files into the same buck target as `JavaJSCallInvokerHolder.{cpp,h}`.
I think these steps should be enough to create the TurboModuleManager without needing a bridge:
1. Make `JSCallInvoker` an abstract base class.
2. On Android, create another derived class of `JSCallInvoker` that doesn't depend on Instance.
3. Create `JavaJSCallInvokerHolder` using an instance of this new class somewhere in C++.
4. Pass this instance of `JavaJSCallInvokerHolder` to Java and use it to create/instatiate `TurboModuleManager`.
Regarding steps 1 and 2, we can also make JSCallInvoker accept a lambda.

Changes our property access pattern to iterate through props once and pass the Object value directly rather than looking the value up in the map with the key.
Note some ViewManagers methods (especially yoga related ones on shadow nodes) expect a `Dyanamic`, so this diff also creates Dynamic's only when needed by the hand-written code, and introduces a new `DynamicWithObject` to create them that simply wraps the underlying object (as opposed to `DynamicWithMap` which wraps the map and does a lookup any time the `Dynamic` is accessed.

Summary:
This mechanism is heavily abused inside of the react-native and inside of the various native modules.
The main problem is that people don't remove their listeners and as result, we have memory leaks.
Some modules like UIManager, NativeAnimatedModule have resources holding Activity context. Those modules are held through a pretty long chain of dependencies.
In order to allow GC to collect those listeners, I replaced the CopyOnWriteSet by WeakHashMap and synchronized access. It is not such a big deal in terms of performance as those listeners are not called/modified too frequently but this prevents hard to debug memory leaks.

Summary:
Instead of using measure specs to set certain yoga properties on the root node (like max width, auto width, specific width), use yoga's calculateLayout(width, height) instead. The measure specs will be stored in the shadow node. This allows us to remove duplicated code that processes the measure specs and allows us to remove other logic like the enableLayoutCalculation() method.
This diff also removes MeasureSpecProvider. MeasureSpecProvider was originally introduced to pass previously measured view measure specs to the initial creation of the root shadow node, but it turns out that this is unnecessary. We can update the root layout specs from the root view instead.

Summary: SizeMonitoringFrameLayout was used to set layout contraints on the root shadow node when the native view's size changes. Since then, we introduced ways for the root node to use proper layout contraints using the root view's measure specs, which provides more accurate constraints for the root node, so SizeMonitoringFrameLayout is no longer needed. This ends up making a lot of UIManagerModule's method signatures cleaner

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

Summary:
DynamicFromMap internally uses SimplePool object to recycle dynamic prop objects. But the pool is not multi-thread safe. Currently the most used dynamic props are size props such as left, paddingVertical, marginTop and so on. These props are only accessed from the layout thread so the pool works fine. If a dynamic prop is needed in UI thread, then the two threads can access the same pool object and cause random errors. This PR make the pool object thread local to avoid synchronization. After this change there are two pool objects created in the process.
Tested in official Airbnb app after updating accessibilityComponentType to be dynamic.
Once this is merged, I'll send another PR to support "disabled" state in `accessibilityComponentType`.

Summary: Moving up when we start the CORE marker to `FbReactFragment.onFragmentCreate` on FB4A. Right now the CORE marker gets started with CREATE_REACT_CONTEXT_START, since it's possible for the instance manager to be created before TTI begins. We address this in HOME_TTI by collecting the getInstanceManager time, comparing to TTI start, and using that as bridgeStartupStartTime. Ideally, though, we'd just start the CORE marker at the right time so we can use it independently to measure RN startup. This diff moves up CORE start time to `onFragmentCreate` (even before `getReactInstanceManager`)
