Unify defaultSource and defaultSrc ImageProp (facebook#47710)

Summary:

There is Android code that supports remapping `defaultSrc` -> `defaultSource` for `ImageNativeComponent`.
The docs reference this prop as `defaultSource`: https://reactnative.dev/docs/next/image#defaultsource
It is not referenced as `defaultSrc` anywhere. Let's unify it as `defaultSource` across both platforms.
