windows: updated copyright notices

Updated the master copyright (for Khronos, Valve, and LunarG) to 2021.

Also identified that the four files containing the MIT copyrights were
last updated by LunarG in 2017, so updated those copyrights (again for
Khronos, Valve, and LunarG) accordingly.

I also corrected the spelling of "open-source".
