Summary:
We ran an experiment to test different implementations of TurboModules HostObjects, as the current one has various inefficiencies, such as re-creating HostFunctions on every property access. The strategy we found to be most efficient and flexible longer-term is to represent the TurboModule with a plain JavaScript object and use a HostObject as its prototype. Whenever a property is accessed through the prototype, we cache the property value on the plain object, so it can be efficiently resolved by the VM for future accesses.

Summary:
TurboCxxModule doesn't use the the default JSI getter that TurboModule offers, and has custom behaviour for `getConstants` which broke the I18nAssets module in the binding experiment.

Summary:
Enables two new experiments (and the current behaviour as default) to speed up access to TurboModule methods from JS.
1) HostObject - Current behaviour
2) Prototype - Connect the TM HostObject via `__proto__`, and cache any methods accessed on the wrapper object.
3) Eager - Eagerly store all methods on the wrapper object, do not expose the HostObject to JS at all (TurboModules no longer need to be HostObjects in this scenario)

Summary:
* Make constructor private, all access is through install()
* Use nullability of longLivedObjectCollection_ instead of separate bool disableGlobalLongLivedObjectCollection_

Summary:
## Android API
```
// Before we initialize TurboModuleManager
ReactFeatureFlags.useTurboModuleJSCodegen = true
```
## iOS API
```
// Before we initialize RCTBridge
RCTEnableTurboModuleJSCodegen(true);
```
## How is the JS Codegen actually enabled?
The above native flags are translated to the following global variable in JavaScript:
```
global.RN$JSTurboModuleCodegenEnabled = true;
```
Then, all our NativeModule specs are transpiled to contain this logic:
```
interface Foo extends TurboModule {
// ...
}
function __getModuleSchema() {
if (!global.RN$JSTurboModuleCodegenEnabled) {
return undefined;
}
// Return the schema of this spec.
return {...};
}
export default TurboModuleRegistry.get<Foo>('foo', __getModuleSchema());
```
Then, in our C++ JavaTurboModule, and ObjCTurboModule classes, we use the TurboModule JS codegen when the jsi::Object schema is provided from JavaScript in the TurboModuleRegistry.get call.

Summary:
This is to prepare for enabling TurboModule on Android. This commit compiles in all the core files (C++) into the ReactAndroid NDK build step. This doesn't yet enable TurboModule by default, just compiling in the infra, just like for iOS.
New shared libs:
* libreact_nativemodule_core.so: The TurboModule Android core
* libreact_nativemodule_manager.so: The TurboModule manager/delegate
To be compatible with `<ReactCommon/` .h include prefix, the files had to move to local `ReactCommon` subdirs.
