[General][Breaking] Use hasteModuleName for C++ Turbo Module enums
This is a follow up to https://github.com/facebook/react-native/pull/44630
This changes the names of C++ Turbo Modules enums to use the `hasteModuleName`.
Example: `NativeMyAbcModule.js` with this spec:
```
export enum EnumNone {
NA,
NB,
}
export interface Spec extends TurboModule {
+getStrEnum: (arg: EnumNone) => EnumStr;t
}
export default (TurboModuleRegistry.get<Spec>('MyAbcModuleCxx'): ?Spec);
```
Before now we generated a base C++ struct with the name:
```
MyAbcModuleCxxEnumNone
^^^
```
Now the generate name is:
```
NativeMyAbcModuleEnumNone
^^^^^^
```
## Changes:
- No `Cxx` injected anymore
- Ensure base struct is `Native` prefixed (all RN JS TM specs start with it)

Summary:
Changelog: [General][BREAKING] Don't support 'float' enums in Turbo Modules
- The current implementation of 'float enums' in C++ does not work as invalid results are returned.
- At potential fix could still cause rounding errors when crossing language bounaries, e.g. `4.6` can become `4.5599999942..`
- C++ enum classes don't support float: https://eel.is/c++draft/dcl.enum#2.sentence-4
> The type-specifier-seq of an enum-base shall name an integral type; any cv-qualification is ignored.
Hence removing the feature of `float enums` for now

Summary:
This enables to code-gen base C++ types for custom exported JS types from a RN TM spec - which have been previously excluded from code-gen as these aren't used in any function.
The only work around so far was to ‘register’ a random function using the custom type which should be used for RCTDeviceEventEmitter events

[Internal] -
Make it possible to call `emitDeviceEvent` from C++ TurboModules without the need to explicitly provide the reference to `jsi::Runtime`, as in some contexts (when we call e.g. not from the JS thread itself) it may be hard to get hold of.

Pull Request resolved: https://github.com/facebook/react-native/pull/41767
Changelog: [Internal]
Adds a simple example showing a direct recursive node in a Cxx TM.
Currently we can't auto-generate [the necessary C++ Types](https://reactnative.dev/docs/next/the-new-architecture/cxx-custom-types#struct-generator) - but we can add it later if this scenarios becomes really common.
Direct recursive nodes, can't be value types - it would require infinite memory. Hence they are nullable and managed by a smart pointer.

Changelog: Internal
Adding a Cxx TM example which adds a listener and returns a subscription to remove that listener from the TM.
You should be able to use this with React Hooks - https://legacy.reactjs.org/docs/hooks-reference.html
E.g.
```
useEffect(() => {
const subscription = NativeCxxModuleExample.setValueCallbackWithSubscription(
callbackValue => // use it
);
return subscription;
});

Summary:
This PR is adding examples of Turbo Modules functions throwing runtime exceptions and asserts. This should make it easier to collaborate and develop the error reporting for a new architecture that is being discussed in the React Native New Architecture Working Group -> https://github.com/reactwg/react-native-new-architecture/discussions/122.
I'm not sure what return type should be used for the JS function returning `Promise<void>` in Cxx, I used [`AsyncPromise<jsi::Value>`](https://github.com/facebook/react-native/pull/36729/files#diff-9cebc75f48fd35fd6fef71138f98dfd0ba28a754b2aab0d6fe44fd685f74ce16R135), what would you use, I've not found `void` type to use?

[INTERNAL] [ADDED] - Error reporting examples in rn-tester turbo modules
Pull Request resolved: https://github.com/facebook/react-native/pull/36729
Test Plan:
This PR doesn't change any RN behavior. Only shows the current state by adding an example to rn-tester.
I'm happy to add these examples to the unit/integration test, just point me to where would be a good place.

Pull Request resolved: https://github.com/facebook/react-native/pull/36581
Found that the current codegen did not properly handle a return type of `?bool` because the branch of `constexpr (is_optional_v<T>)` assumed that T was always a JSI value that needed conversion, and `supportsToJs<bool, bool>` is false.

Pull Request resolved: https://github.com/facebook/react-native/pull/36030
Generate enum types in c++ turbo modules.
For enums in the ts schema file such as:
```
export enum NumEnum {
ONE = 1,
TWO = 2,
}
```
This would export enums and the relevant Bridging to js and from js code to the spec H files such as:
```
#pragma mark - SampleTurboModuleCxxNumEnum
enum SampleTurboModuleCxxNumEnum { ONE, TWO };
template <>
struct Bridging<SampleTurboModuleCxxNumEnum> {
static SampleTurboModuleCxxNumEnum fromJs(jsi::Runtime &rt, int32_t value) {
if (value == 1) {
return SampleTurboModuleCxxNumEnum::ONE;
} else if (value == 2) {
return SampleTurboModuleCxxNumEnum::TWO;
} else {
throw jsi::JSError(rt, "No appropriate enum member found for value");
}
}
static jsi::Value toJs(jsi::Runtime &rt, SampleTurboModuleCxxNumEnum value) {
if (value == SampleTurboModuleCxxNumEnum::ONE) {
return bridging::toJs(rt, 1);
} else if (value == SampleTurboModuleCxxNumEnum::TWO) {
return bridging::toJs(rt, 2);
} else {
throw jsi::JSError(rt, "No appropriate enum member found for enum value");
}
}
};
```
That code would allow us to use these enums in the cxx files like this:
```
NativeCxxModuleExampleCxxEnumInt getNumEnum(
jsi::Runtime &rt,
NativeCxxModuleExampleCxxEnumInt arg);
```

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35138
Changelog:
[General][Added] - Add a C++ only TurboModule example (for Android/iOS/macOS/Windows)
react-native@0.69 introduced a new bridging layer to ease integration for pure C++ TurboModules using C++ std:: types directly instead of the lower level jsi:: types:
https://github.com/facebook/react-native/tree/v0.69.0/ReactCommon/react/bridging
This bridging layer can be used in JSI functions or more conveniently in C++ TurboModules.
Here is a example of an C++ only TurboModule which will work on Android and iOS and macOS/Windows (using microsoft/react-native-macos|windows) only using flow/TypeScript and standard C++ types.
C++ only TurboModules are very handy as they do not require to work with JSI APIs - instead std:: or custom C++ can by used.
