Migrate RCTDevSettings to RCTBundleManager
Migrate RCTDevSettings to RCTBundleManager

Summary:
This diff migrated RCTDevSettings to the RCTBundleManager, which works both in bridge/bridgeless mode. RCTDevSettings is the last TurboModule that synthesizes the bundleURL. So, after this diff, we can get rid of the RCTBundleHolderModule protocol.
