Modify ViewManager.receiveCommand to call into delegate (#37070)

Summary:
Pull Request resolved: #37070

This diff fixes an issue where codegened native commands are not able to be triggered, as codegen adds command handling to the delegate. This also brings how receiveCommand is handled into parity with how setProperties is called on the delegate.
