nvim: Reintroduce clipboard settings

clipboard support just seems to be completely flaky right now. Add
previous settings but instead of tmux specific commands use wayland
clipboard tools.

This should make it work everywhere. One downside of this setting is
we go back to polluting system clipboard every time & does not really
matter if we copy to + or * register. Both will result in a call to
wl-copy.
