feat(clipboard): support g:clipboard="osc52" #33021

Browse Source 
Problem:
Forcing Neovim to use OSC52 for the system clipboard should be simple
and concise, since OSC52 is widely supported (Alacritty, Ghostty,
iTerm2, WezTerm, Kitty, xterm, tmux, etc.) and is the most portable
approach for syncing clipboards across SSH.

Solution:
Support g:clipboard="osc52".
