Clean up all old uses of FuzzInterface interface

This CL converts remained old Mojo types of FuzzInterface
interface to new Mojo types. Major changes are as below,

  - Convert mojom::InterfaceFactoryPtr to
    mojo::PendingRemote|Remote<mojom::FuzzInterface>
  - Convert mojo::InterfaceFactoryRequest to
    mojo::PendingReceiver<mojom::FuzzInterface>
  - Convert mojo::Binding to mojo::Receiver
