ovs: Turn vports with dependencies into separate modules
The internal and netdev vport remain part of openvswitch.ko. Encap vports including vxlan, gre, and geneve can be built as separate modules and are loaded on demand. Modules can be unloaded after use. Datapath ports keep a reference to the vport module during their lifetime. Allows to remove the error prone maintenance of the global list vport_ops_list.
