There are 2 issues:
* RCTTurboModuleManager may be initialized too late, so the module lookup from native via `[bridge moduleForClass:]` may end up going to the old system incorrectly
* In the case where JS is asking for a nativemodule, we may be incorrectly registering modules that are marked as RCTTurboModule - they should be ignored instead

Summary:
`CatalystInstanceImpl.cpp` now depends on `JSCallInvoker` and `JavaJSCallInvokerHolder`. Therefore, we need to correctly adjust the OSS builds to include these dependencies into the `libreactnativejni.so` file.
I made `ReactCommon/turbomodule/jscallinvoker` a static library `libjscallinvoker.a`. I then made `ReactAndroid/src/main/jni/react/jni`'s `libreactnativejni.so` depend on that static library. Also, because the Android NDK build system doesn't support header namespaces, I had to use the filesystem to simulate them. This is why all the `.cpp` and `.h` files for `JSCallInvoker` were moved to a `jsireact` folder.

Summary:
`TurboModuleManagerDelegate` is an abstract base class with the following API:
```
public TurboModule getModule(String name, ReactApplicationContext reactApplicationContext);
public CxxModuleWrapper getLegacyCxxModule(String name, ReactApplicationContext reactApplicationContext);
```
```
std::shared_ptr<TurboModule> getTurboModule(std::string name, jni::global_ref<JTurboModule> turboModule, std::shared_ptr<JSCallInvoker> jsInvoker) override;
std::shared_ptr<TurboModule> getTurboModule(std::string name, std::shared_ptr<JSCallInvoker> jsInvoker) override;
```
On the C++ side, when asked to provide a TurboModule with name `name`:
1. First, is this a CxxModule? If so:
1. Create the CxxModule and return
2. Otherwise:
1. Somehow get a Java instance of the TurboModule
2. If this Java object represents a CxxModule, like `FbReactLibSodiumModule`:
1. Grab the C++ part of this object, and wrap it in a `TurboCxxModule.cpp` and return.
3. Otherwise:
1. Wrap the Java object in a C++ HostObject and return.
This pseudocode demonstrates how we'd use `TurboModuleManagerDelegate` to implement `__turboModuleProxy`.
```
__turboModuleProxy(name, jsCallInvoker):
let cxxModule = TurboModuleManagerDelegate::getTurboModule(name, jsCallInvoker)
if (!cxxModule) {
return cxxModule;
}
// JNI Call that forwards to TurboModuleManagerDelegate.getLegacyCxxModule
let javaCxxModule : CxxModuleWrapper = TurboModuleManager.getLegacyCxxModule(name)
if (!javaCxxModule) {
return std::shared_ptr<react::TurboCxxModule>(javaCxxModule.getModule())
}
// JNI Call that forwards to TurboModuleManagerDelegate.getModule
let javaModule : TurboModule = TurboModuleManager.getModule(name)
if (!javaCxxModule) {
return TurboModuleManagerDelegate::getTurboModule(name, javaModule, jsCallInvoker)
}
return null

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.

Luckily, it does not need a complex feature-full map (which is not free to allocate and use), it needs a tiny map with a dozen values. Why do we need to pay for what we don't use?

Summary:
Previously we computed the list of nodes that need to be notified about layout changes using a list of mutation instructions. That was fine, but that's not really compatible with some other changes that I plan to make, so I decided to change it (make it better).
Besides the better design (debatable; fewer dependencies to unrelated moving pieces), here is why I believe the new way is more performant:
* The new approach has no `dynamic_casts`, whereas the previous has tons of them (two per a mutation). If a `dynamic_cast` takes 10 ns, for 500 nodes it can take up to 5ms only for casts. (Non-scientific assumption.)
* After removing dependency to mutation instruction, we can enable flattening for views which have `onLayout` event.

Summary:
Different frameworks use different kinds of floats, optional floats, and floats with assigned unit names. All those approaches use different ways to represent undefined and empty values. To deal with it we need to have some helper functions.
So, this diff changes some ways that we convert some corner values (like NaN and empty value). That change is motivated by recent personal discoveries in this field that shifted my vision on that. E.g. ComponentKit does not use `CGFloatMax` value as `Infinite` value. UIKit is also (surprisingly to me) okay with using `Infitite` instead of `CGFloatMax`. And, in general, seems using really conceptually appropriate values (instead of UIKit-inspired ones) it's the right thing to do.

At the same time usage of `kFloatMax` was replaced with `Infinity` (which is a different value). Using `max` instead of `Infinity` was an attempt to mimic iOS/UIKit model where `Infinity` and `NaN` values usually are not being used. However, now this does not seem like a good idea. This concept is not used anywhere else (even in CK which is totally incompatible with it) and de-facto in RN we use it only in few places. So, let's use Infinity in places where it's logically appropriate.

Summary:

Adds `YGStyle::ValueRepr` to make code depending on the actual type easier to write.
So far, we have treated `yoga::detail::CompactValue` as an implementation detail, and that’s what it’s supposed to stay.
React Native Fabric has one value conversion overload that depends on that type, though, and used `decltype(YGStyle{}.margin()[0])` until now.
That’s problematic for two reasons:
- we want to constrain the parameter of `operator[](...)` to enum types, making the `0` unsuitable
- we want to return the non-const overload of the operator to return a custom `Ref` type, which is not the type needed by Fabric.
Making the storage type explicit allows to write more forward-compatible code.
