https://github.com/void-linux/void-packages/pull/43728

vivaldi: update to 6.0.2979.18, support user flags, adopt.
*marking as draft while I ask upstream for clarification on redistribution permission*

will now read the contents of `$XDG_CONFIG_HOME/vivaldi-stable.conf` and pass that to the underlying binary

patch comes from arch

for example, to force `prefers-color-scheme: dark` and work on wayland:
```
$ cat ~/.config/vivaldi-stable.conf
--force-dark-mode --ozone-platform-hint=auto
```

missing dependencies libnotify and xdg-utils also added
