Add HostFunction handling to _scheduleOnJS

[bartlomiejbloniarz]

Summary

Currently, when a Host Function is called through runOnJS the app crashes, since we are only handling Remote Function in the _scheduleOnJS method. For example the following code leads to a crash:

useEffect(() => {
    const id = setInterval(() => {
      console.log('interval');
    }, 1000);
    const intervalAlias = clearInterval;
    runOnUI(() => {
      runOnJS(intervalAlias)(id);
    })();
  }, []);

This example works fine on the old architecture, because Timer functions are polyfilled there. On the New Architecture they are Host Functions, so we need to handle them separately.

Test plan

Check

useEffect(() => {
    const id = setInterval(() => {
      console.log('interval');
    }, 1000);
    const intervalAlias = clearInterval;
    runOnUI(() => {
      runOnJS(intervalAlias)(id);
    })();
  }, []);
