datapath-windows: Add port friendly name to OVS_VPORT_ENTRY
The port friendly name will be set by WMI / powershell script.
It will be used from within the netlink command vport new to
identify the hyper-v switch port it represents.
This patch also adds a function to lookup a vport by the
port friendly name.
