  datapath-windows: Add GRE TEB support for windows datapath

This patch introduces the support for GRE TEB (trasparent ethernet bridging)
for the windows datapath.

The GRE support is based on http://tools.ietf.org/html/rfc2890, without
taking into account the GRE sequence, and it supports only the GRE protocol
type 6558 (trasparent ethernet bridging) like its linux counterpart.

Util.h: define the GRE pool tag
Vport.c/h: sort the includes alphabetically
     add the function OvsFindTunnelVportByPortType which searches the
     tunnelVportsArray for a given port type
Actions.c : sort the includes alphabetically
      call the GRE encapsulation / decapsulation functions when needed
Gre.c/h : add GRE type defines
    add initialization/cleanup functions
    add encapsulation / decapsulation functions with software offloads
    (hardware offloads will be added in a separate patch)
    support

Tested using: PSPING
        (https://technet.microsoft.com/en-us/sysinternals/psping.aspx)
        (ICMP, TCP, UDP) with various packet lengths
        IPERF3
        (https://iperf.fr/iperf-download.php)
        (TCP, UDP) with various options

Allow STT encapsulation to take place in the case we have a TCP payload
without LSO.
