Introduce ImageRequestParams (facebook#47723)

Summary:
Pull Request resolved: facebook#47723

Identity of `ImageRequest` is based on `ImageSource` and a subset of `ImageProps`. If any of those change, the request must be recreated and resubmitted.

Currently, the relevant subset of ImageProps is represented by a single `blurRadius` prop. This list will grow in the future. In order to simplify adding new props to the image request, we introduce the `ImageRequestParams` type that will wrap all the relevant props.

The alternative approach to pass `ImageProps` directly to `ImageManager` is worse because it would introduce dependency cycle between `ImageManager` and the `Image` component, and also it would require to store the props in State, which is bad.

Changelog: [Internal]
