Summary:
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);
```

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.
