Bug 1129 - NEWT MonitorDevice's physical size on Windows must be read via EDID

On Windows, one must read the monitor's EDID data as stored in the registry,
no 'simple' API works otherwise.

The proper way requires utilizing the Windows Setup-API.

This code is inspired by Ofek Shilon's code and blog post:
   <http://ofekshilon.com/2014/06/19/reading-specific-monitor-dimensions/>
   See: function 'NewtEDID_GetMonitorSizeFromEDIDByModelName'

In contrast to Ofek's code, function 'NewtEDID_GetMonitorSizeFromEDIDByDevice'
uses the proper link from
     DISPLAY_DEVICE.DeviceID -> SP_DEVICE_INTERFACE_DETAIL_DATA.DevicePath,
where DISPLAY_DEVICE.DeviceID is the monitor's enumeration via:
     EnumDisplayDevices(adapterName, monitor_idx, &ddMon, EDD_GET_DEVICE_INTERFACE_NAME);
Hence the path to the registry-entry is well determined instead of just comparing
the monitor's model name.
