Remove unreferenced JSEngineResolutionAlgorithm from ReactHost API (#45269)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/45269

There's no callers to this property, and we already create a `jsRuntimeFactory` above in DefaultReactHost, which will actually decide which VM to use.
