[Feature] Option to enable address bar/tool bar/bookmarks bar

[deregtd]

I'm experimenting with using the balena-wpe block to replace the balena-browser block on a rpi that has a small touchscreen that connects to a local grafana website. However, any time the grafana container is updated, the browser requires a hard refresh to make it connect for a new instance id or something. So right now I need to reboot the entire rpi to get the browser to restart.

The wpe webkit setup here has no address or toolbar, nor does it seem to respond to any touch gestures that might initiate a refresh, so I'm out of ideas after playing around for a while. I have some other handy uses for enabling the bookmarks bar, for example, if that were to be possible, and hardcode a bookmarks.html file into the container to use.

In the balena-browser block, I just left it out of kiosk mode so it had the full address/toolbar to allow refreshing, which unblocked my scenarios, though not perfectly of course. :)

Thanks for the project, though, it's so much faster than the X11-based ancient webkit in the balena-browser project!
