patch 9.0.1684: Update libvterm to rev 839
Commit: https://github.com/vim/vim/commit/b00df7aa388994119346a21d77b0d0db2a0a5e9f

patch 9.0.1684: Update libvterm to rev 839
Problem: libvterm slightly outdated
Solution: Update libvterm from rev 818 to rev 839
Notable fix: libvterm now handles DECSM/DECRM with multiple arguents,
so several ncurses programs (e.g. nnn) can enable mouse properly when
run in Vim's terminal in XTerm.
