  datapath-windows: Add function to get continuous buffer from context

This patch extracts the code that tries to get a continuous IPv4 header
buffer from the function 'OvsUpdateIPv4Header' and moves it to a new
function 'OvsGetHeaderBySize'.

The new function can be used later when trying to change the UDP/TCP/MPLS
etc., headers.

  datapath-windows: Add support for OVS_KEY_ATTR_UDP set action

This patch adds support for set action with OVS_KEY_ATTR_UDP attribute
(change UDP source or destination port).

If the source or destination UDP port was changed, update the UDP checksum.

A sample flow can look like the following:
set(udp(src=67,dst=68))
