Subject: [PATCH] Add the Sync non-standard capability for synchronized updates
 to terminfo

Since the geniuses at terminal-wg are trying their best to create chaos
by retroactively changing the escape code used for this feature, it is
good to have a property for it in terminfo. Since tmux already uses Sync
for it, follow that in kitty's terminfo.
