Implement OSC52 functionality to use clipboard

[mjmar01]

Is your feature request related to a problem? Please describe.

There are some CLI tools that can set clipboard content to enhance workflows. These tools currently don't work completely in terminator.

Describe the solution you'd like

Other terminal emulators often support OSC-52 escape sequences which allows this functionality. See: https://www.reddit.com/r/vim/comments/k1ydpn/a_guide_on_how_to_copy_text_from_anywhere/

Describe alternatives you've considered

Alternative would be to not use terminator ):

That doesn't work for me

Additional context

Originally grabbed my attention when using soft-serve. This could also be used as a test case:

ssh git.charm.sh
# Press "c" to copy clone URL
# -> Not in clipboard

OSC52 is ... a very contentious feature. It is not on the roadmap currently as it is seen as too ripe for abuse. See https://gitlab.gnome.org/GNOME/vte/-/issues/2495 for far too many gory details
