Summary:
Sometimes, when we deal with ImageRequest and ImageResponseObserverCoordinator we subscribe for status (or access the coordinator) without owning an ImageRequest. In those cases, we have to retain the coordinator explicitly.
For those cases, ImageRequest now exposes `ImageResponseObserverCoordinator` as a `std::shared_ptr`.
Eg, concretely in the code, `completionBlock` and `progressBlock` copied a raw pointer to the observer inside which can lead to a crash when ImageRequest is being deallocated before we received an image data.

Summary: Don't use shared_ptr in this case, it's not needed.

Summary: Folly promises/futures have been replaced by an observer model which keeps track of loading state. This resolves at least one crash that I can no longer repro and simplifies the code a bit (IMO).

Summary: This diff fixes the release of ImageRequest object. The responseFutureSplitter_ can be destroyed by the time ~ImageRequest is executed. See P60163877 for original crash (this crash was reproducible when reloading or closing a Fabric screen that contains several images.
