Michał Osadnik 929c5d7c10 Add support for promises
Summary:
This diff add support for promises. It wraps promise's type into a special type annotation.

#Facebook
Currently the shape of promises parsing is:

```
{
  name: 'getValueWithPromise',
  optional: false,
  typeAnnotation: {
    type: 'FunctionTypeAnnotation',
    params: [
      {
        name: 'error',
        typeAnnotation: {
          type: 'BooleanTypeAnnotation',
        },
      },
    ],
    returnTypeAnnotation: {
      type: 'GenericTypeAnnotation',
      typeId: {
        hasteModuleName: 'NativeSampleTurboModule',
        name: 'Promise',
      },
      typeParameters: [
        {
          type: 'StringTypeAnnotation',
        },
      ],
    },
    returnTypeNameOverride: null,
  },
  rawTypeAnnotation: '(error: boolean) => Promise<string>',
  documentation: null,
};

```

which is a bit unclear for me. I suggest sth way more easier:

```
{
  "modules": {
    "SampleTurboModule": {
      "nativeModules": {
        "SampleTurboModule": {
          "properties": [
            {
              "name": "getValueWithPromise",
              "typeAnnotation": {
                "type": "FunctionTypeAnnotation",
                "returnTypeAnnotation": {
                  "type": "PromiseTypeAnnotation",
                  "resolvingType": {
                    "type": "StringTypeAnnotation"
                  }
                },
                "params": [
                  {
                    "name": "error",
                    "typeAnnotation": {
                      "type": "BooleanTypeAnnotation"
                    }
                  }
                ]
              }
            }
          ]
        }
      }
    }
  }
}
```

However, I'd be happy to see some feedback / other solutions as well!
