Delete ImageRequest::~ImageRequest (#37222)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37222

changelog: [internal]

User defined destructor does not make sense here. ImageRequest is owned by ImageState, which is owned by ImageShadowNode. ImageShadowNode requires garbage collection from the runtime to be destroyed. Calling cancel in dtor is not deterministic and that is undesired.
