Remove babel transforms for flipper-server

Summary: Flipper server itself requires no babel transforms. We applied extra transforms only for the bundled plugins. However, we pack and ship all plugins in the /static folder. They are always available on the FS. Therefore we could stop bundling any plugins into flipper-server's source code.
