GHOST: refresh standard cursors available for platforms

* Add more standard cursor types, that platforms can optionally support.
* Remove a few unused cursor types that were not properly supported and
  would show the wrong cursor when used.
* Add native cursor files for Windows. These scale well with DPI and have
  anti-aliasing. Designed by Duarte Farrajota Ramos.
