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:
Pull Request resolved: https://github.com/facebook/react-native/pull/33413
This moves `CallbackWrapper` and `LongLivedObject` into a new "bridging" library. This library is mostly intended for use by the native module system, but can also be used separately to "bridge" native and JS interfaces through higher-level (and safer) abstractions than relying JSI alone.

Not having this disallows including turbo module and extending in places where RTTI is enabled.
There is no additional includes or implementation changes - it merely allows for things to nicely link with other libraries.
Changelog: [General][Fixed] - Allow including TurboModule.h in mixed rtti/no-rtti environment, even if TurboModule.h/cpp is compiled without RTTI.

Summary:
JSI callbacks are only destroyed if the callback is called. If the callback is never called, we're potentially leaking a lot of callbacks.
To mitigate this, we add a wrapper object that is owned by the std::function. Whenever the std::function is destroyed, the wrapper is destroyed and it deallocates the callback as well.

[Internal] [Fixed] - Fix various C++ warnings
Pull Request resolved: https://github.com/facebook/react-native/pull/31002
Test Plan:
Almost all the changes here are simply making explicit conversions which are already occurring. With the exception of a couple of constants being changed from doubles to floats.
With these changes I am able to remove a bunch of warning suppressions in react-native-windows.

Summary:
The TurboModuleUtils.h includes "folly/Optional.h" which is not used and creates an unnecessary dependency on Folly.
In this PR we remove this unnecessary include.
It is required for the https://github.com/microsoft/react-native-windows/pull/6804 where we add an experimental support for the C++ TurboModules. While the C++ TurboModules use the same JSI and TurboModule code defined in react-native, we provide a layer that let them to work over the ABI-safe Microsoft.ReactNative.dll boundary. The RNW Nuget distribution with DLL files includes a few source files to create native/turbo modules that work through the ABI-safe API. The TurboModuleUtils.h is one of such files. By removing the dependency on Folly we reduce requirements for the native module code. After this PR is merged we will remove the fork of the TurboModuleUtils.h added in https://github.com/microsoft/react-native-windows/pull/6804.
## Changelog
[Internal] [Fixed] - Remove dependency on Folly in TurboModuleUtils.h
Pull Request resolved: https://github.com/facebook/react-native/pull/30672
Test Plan:
The change does not bring any functional changes. It may only affect code compilation where some code may depend on TurboModuleUtils.h when it needs the "folly/Optional.h". The fix is add the `#include <folly/Optional.h>` there explicitly.
I had run the iOS tests and they passed:
```
yarn
pod install in packages\rn-tester
./scripts/objc-test.sh test
```

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:
## Previously
- When TurboModules system was on, we'd only log events from the TurboModules system.
- When TurboModules system was off, we'd only log events from the NativeModule system.
This ultimately gives us less data to analyze both systems in production.
## Changes in This Diff
When perf. logging is on, we'll log events from both systems. Each QPL event now include an annotation of which system the event is coming from. Concretely, this will allow us to see how much of the NativeModule system is being exercised in the TurboModule test group.

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.
