pass in bundle url as a dependency of RCTHost (#37568)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37568

Changelog: [Internal]

since bundleURL is constant throughout an app session, we should pass it in as a dependency from above. in the next diff, i'll get rid of `getBundleURL` from the react host's delegate.
