Ramanpreet Nara 6d6e04619f Fix ObjC++ structs and method mapping
Summary:
Adjust generated ObjC++ code to resolve a few build time and run time errors:

* Suppress CONSTANTS struct implementations
* Use type alias name as struct name when serializing arguments that involve a type alias
* Use actual number of arguments for a method when generating method map.

With these changes in place, RNTester can be built and run using the code that is generated by the new codegen.

Ramanpreet Nara 97d3e85c29 Fix ObjC++ module generator output
Summary:
* Removed extraneous closing brace.
* Fixed static method signature, replacing double colon with an underscore (`static facebook::jsi::Value __hostFunction_Native${moduleName}SpecJSI::${methodName}()` -> `static facebook::jsi::Value __hostFunction_Native${moduleName}SpecJSI_${methodName}()`).
* Wrap `getConstants` selector name with `selector()`.
* Pass through `getConstants` and `constantsToExport` to allow de-duping of `getConstants` method in generator output.

Note that the FBReactNativeSpec that is output by the generator still has some issues that need to be addressed before it can be used.

Ramanpreet Nara 1ac1255d63 E2E snapshot test ObjC++ generator
Summary:
NativeModule specs exist under `react-native-github/packages/react-native-codegen/src/__tests__/modules/fixtures`. `GenerateModuleObjCpp-test.js` runs the RN Codegen on those NativeModule specs, and saves the output inside a snapshot. For convenience, the folowing command runs the legacy codegen on the fixtures:

```
buck build fbsource//xplat/js/react-native-github/packages/react-native-codegen/src/__tests__/modules:RNCodegenModuleFixtures-flow-types-ios --show-output
```
