Summary: This was an experiment to patch individual deltas in development instead of reloading the whole JS bundle. With improvements such as Fast Refresh that reduces the need for reloads and bundle splitting that reduces the number of modules and memory by 10x, we won't be needing this complex optimization that we never properly made work. This diff removes that code and I will be removing the JS side of things in Metro in a follow-up diff.

Summary:
There have been multiple complaints about combining RN with various
other FB libraries, including Litho and Flipper, because of bundled dependencies
that can't be deduplicated by Gradle.
This is one of three current conflicts:
1) Proguard annotations (this PR)
2) Yoga
3) fbjni
While the Yoga group name doesn't make a massive amount of sense
it was the easiest existing package to use and since we don't
have a better namespace for this, we might as well use this.
A similar change to Litho is landing right now.

Summary: ModuleRegistryBuilder does as assertion to verify that all `cxxModules` are instances of `CxxModuleWrapperBase::javaStaticClass()`. This assertion is causing the crash in T48554656. Since we don't know which NativeModule is causing this problem, it's difficult to get to the bottom of this. So, for now, I'm improving the assertion message in the hopes that it helps us get to the bottom of this issue.

Summary:
This diff introduces an interface `ViewManagerDelegate` and its base implementation `BaseViewManagerDelegate`, which is used as a parent class for all view manager delegates generated by the JS codegen. Before the changes in this diff, generated delegates didn't support setting the base view properties such as background color, rotation, opacity, etc. Now it's possible to do by using `BaseViewManagerDelegate.setProperty(...)`, and since all generated delegates extend BaseViewManagerDelegate, they can just call `super.setProperty(...)` for properties they don't want to handle.
This diff also introduced a new method `ViewManager.getDelegate()`. This will allow view managers to return an instance of the delegate generated by JS and ensure that the view properties are set in a type-safe manner. If this method returns null (it does by default), we fall back to the default implementation of setting view properties using Java-generated `$$PropsSetter`
classes.
This is an example of an interface class generated by JS:
```
public interface RCTAxialGradientViewViewManagerInterface<T extends View> {
void setColors(T view, Nullable ReadableArray value);
void setLocations(T view, Nullable ReadableArray value);
void setEndX(T view, Float value);
void setEndY(T view, Float value);
void setStartX(T view, Float value);
void setStartY(T view, Float value);
}
```
This is an example of a delegate class generated by JS:
```
public class RCTAxialGradientViewManagerDelegate<T extends View, U extends BaseViewManager<T, ? extends LayoutShadowNode> & RCTAxialGradientViewManagerInterface<T>> extends BaseViewManagerDelegate<T, U> {
public RCTAxialGradientViewManagerDelegate(U viewManager) {
super(viewManager);
}
Override
public void setProperty(T view, String propName, Nullable Object value) {
switch (propName) {
case "colors":
mViewManager.setColors(view, (ReadableArray) value);
break;
case "locations":
mViewManager.setLocations(view, (ReadableArray) value);
break;
case "endX":
mViewManager.setEndX(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "endY":
mViewManager.setEndY(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "startX":
mViewManager.setStartX(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "startY":
mViewManager.setStartY(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
default:
super.setProperty(view, propName, value);
}
}
}
```
NOTE: What if a view manager, for instance ReactAxialGradientManager, wanted to add support for the borderRadius prop? In the old Java codegen, it would just need to create a method and annotate it with ReactProp (name = ViewProps.BORDER_RADIUS) and $$PropsSetter would call this method when a property with this name must be set. With the new JS codegen, borderRadius is a part of the basic view props, so setBorderRadius is not generated as a part of the ViewManagerInterface, so it’s not possible to set this value. I see two options: 1) add a method boolean setProperty (String propName, Object value) and let the view manager handle it in a non-type safe way (return true if it’s been handled). 2) Generate BaseViewManagerInterface which will include all basic view props and make BaseViewManager implement this interface, leaving all methods empty so that it stays compatible with the current implementation. Override these methods in a view manager that needs to handle a specific property in a custom way (so we would override setBorderRadius in ReactAxialGradientManager).

Summary:
## The Problem
1. `CatalystInstanceImpl` indirectly holds on to the `jsi::Runtime`. When you destroy `CatalystInstanceImpl`, you destroy the `jsi::Runtime`. As a part of reloading React Native, we destroy and re-create `CatalystInstanceImpl`, which destroys and re-creates the `jsi::Runtime`.
2. When JS passes in a callback to a TurboModule method, we take that callback (a `jsi::Function`) and wrap it in a Java `Callback` (implemented by `JCxxCallbackImpl`). This Java `Callback`, when executed, schedules the `jsi::Function` to be invoked on a Java thread at a later point in time. **Note:** The Java NativeModule can hold on to the Java `Callback` (and, by transitivity, the `jsi::Function`) for potentially forever.
3. It is a requirement of `jsi::Runtime` that all objects associated with the Runtime (ex: `jsi::Function`) must be destroyed before the Runtime itself is destroyed. See: https://fburl.com/m3mqk6wt
### jsi.h
```
/// .................................................... In addition, to
/// make shutdown safe, destruction of objects associated with the Runtime
/// must be destroyed before the Runtime is destroyed, or from the
/// destructor of a managed HostObject or HostFunction. Informally, this
/// means that the main source of unsafe behavior is to hold a jsi object
/// in a non-Runtime-managed object, and not clean it up before the Runtime
/// is shut down. If your lifecycle is such that avoiding this is hard,
/// you will probably need to do use your own locks.
class Runtime {
public:
virtual ~Runtime();
```
Therefore, when you delete `CatalystInstanceImpl`, you could end up with a situation where the `jsi::Runtime` is destroyed before all `jsi::Function`s are destroyed. In dev, this leads the program to crash when you reload the app after having used a TurboModule method that uses callbacks.
## The Solution
If the only reference to a `HostObject` or a `HostFunction` is in the JS Heap, then the `HostObject` and `HostFunction` destructors can destroy JSI objects. The TurboModule cache is the only thing, aside from the JS Heap, that holds a reference to all C++ TurboModules. But that cache (and the entire native side of `TurboModuleManager`) is destroyed when we call `mHybridData.resetNative()` in `TurboModuleManager.onCatalystInstanceDestroy()` in D16552730. (I verified this by commenting out `mHybridData.resetNative()` and placing a breakpoint in the destructor of `JavaTurboModule`). So, when we're cleaning up `TurboModuleManager`, the only reference to a Java TurboModule is the JS Heap. Therefore, it's safe and correct for us to destroy all `jsi::Function`s created by the Java TurboModule in `~JavaTurboModule`. So, in this diff, I keep a set of all `CallbackWrappers`, and explicitly call `destroy()` on them in the `JavaTurboModule` destructor. Note that since `~JavaTurboModule` accesses `callbackWrappers_`, it must be executed on the JS Thread, since `createJavaCallbackFromJSIFunction` also accesses `callbackWrappers_` on the JS Thread.
For additional safety, I also eagerly destroyed the `jsi::Function` after it's been invoked once. I'm not yet sure if we only want JS callbacks to only ever be invoked once. So, I've created a Task to document this work: T48128233.

But the reason why we need to make this a global ref is because `JavaTurboModule` needs it to be a global reference for method calls. Making this a `jni::global_ref` from the perspective to TurboModuleManager doesn't really make any sense. So, this diff refactors that bit of code.

## Description
When we reload the app, `ReactApplicationContext.destroy()` is called. This method calls `CatalystInstanceImpl.destroy()`, which (on the NativeModules thread) calls `NativeModuleRegistry.notifyJSInstanceDestroy()`, which loops over all its `ModuleHolder`s, and calls `ModuleHolder.destroy()`, each of which call their NativeModule's `onCatalystInstanceDestroy()` method.
TurboModuleManager is a `JSIModule`, so it also has its `onCatalystInstanceDestroy()` method called when the `ReactApplicationContext` is destroyed. But `TurboModuleManager.onCatalystInstanceDestroy()` doesn't do anything. Instead, at the very least, it should call `onCatalystInstanceDestroy()` of all NativeModules.
