Reland "Introduce bundle-specific native libraries"

This is a reland of 50ab16b8

Original change's description:
> Introduce bundle-specific native libraries
> 
> This will allow native code to be stripped out of the main library
> when it moves to a Dynamic Feature Module.  For now, the libraries will
> be identical.
