editor/evil: use evil-set-cursor-color

Browse source 
set-cursor-color causes an expensive redraw. Plugins like treemacs may
silently change window focus, triggering these calls and causing
freezing. We use evil-set-cursor-color instead, which avoids
set-cursor-color unless the cursor's color has changed.
