The type definitions for `Image` are unnecessarily complicated, and got even more complicated after the changes for the new multiplatform support in Flow.
We had a `Image.js.flow` and a `Image.flow.js` files (which was confusing) and duplicated type definitions in `Image.js.flow`, `Image.android.js` and `Image.ios.js` because all type definitions in the shared module signature must be defined in the platform-specific modules as well.
This moves all type helpers to a new `ImageTypes.js.flow` file, simplifies the common `Image` module interface (to only define the default export type that the platform-specific module must define) and simplifies the Android and iOS specific versions.
As an added benefit, this also improves Flow type coverage by removing a bunch of FlowFixMe comments.
