datapath-windows: Rename hyper-v switch port and nic handlers

Functions such as OvsCreatePort are vague in regard to who creates it or
when. It wasn't a problem thus far, since the vports were created,
updated and destroyed from one place only (hyper-v switch part). But
now, with the netlink implementation of the vport commands, a part of
the vport is constructed by the netlink vport add, and the other part
is constructed by the hyper-v switch nic and port handlers.

This patch renames the hyper-v switch nic and port handlers, so that
they are now prefixed by "Hv" instead of "Ovs", in order to clarify
which of the functions are nic or port handlers. This will make more
clear the usages from netlink vport commands side and from hyper-v
switch side. It will also make more obvious which nic and port
functions are helper functions.
