[windows] retrieve logical DPI, physical resolution and more display information

[ffiirree]

As described in the issue #66 , the infoware can not retrieve correct logical DPI and physical resolution of each display: Before:

Displays:
    #1:
      Resolution  : 2560x1440
      DPI         : 96
      Colour depth: 32b
      Refresh rate: 59Hz
    #2:
      Resolution  : 1280x720
      DPI         : 96
      Colour depth: 32b
      Refresh rate: 50Hz

Now:

  Displays:
    #1:
      Resolution  : 2560x1440
      Logical DPI : 96
      Colour depth: 32b
      Refresh rate: 59Hz
      Position    : 0, 0
      Scale factor: 100%
      Primary     : 1
      Orientation : Landscape
    #2:
      Resolution  : 1920x1080
      Logical DPI : 144
      Colour depth: 32b
      Refresh rate: 50Hz
      Position    : -1079, -1080
      Scale factor: 150%
      Primary     : 0
      Orientation : Landscape (flipped)

The behavior:

• >= Windows 10 1607 : works fine
• < Windows 10 1607 : the values of Logical DPI and Scale factor depend on the global DPI avareness setting
• < Windows 8.1 : needs tests
