console.lua: use native clipboard property on win32 and wayland

Since native clipboard is implemented on win32 and wayland,
use the clipboard property instead.

This fixes the problems with commandline implementations of clipboard:
- On win32, the powershell implementation is complex, and it can take
  several seconds to run for the first time.
- On wayland, it requires wl-paste to be installed, which isn't always
  available. It also works poorly on GNOME.
