Subject: [PATCH] add cut/copy/paste keys

The origin of these keys are old sun keyboards.
They are getting picked up by the custom (progammable) keyboard scene
(see https://github.com/manna-harbour/miryoku for a popular layout).
Support in ghosty is quite handy because it allows to bind copy/paste in
a way that doesn't overlap with ctrl-c/ctrl-v, which can have special
bindings in some terminal applications.
