This should significantly simplify these panels, by not forcing
them to override GObject.constructed all the time. Most panels
were quite straightfoward.
AdwActionRow handles many of the properties we use
CcListRow for. We can re-use it instead of re-creating it.
CcListRow is now an AdwActionRow with three suffixes.
The `activatable-widget` is set when the switch is visible.
Since our `icon-name` property was only used for the arrow
icon, it has been replaced with a `show-arrow` property.
The `bold` property has been removed - it was only used in
one place, and it's not a pattern used in other apps.
I decided to go this route because replacing all the
instances of CcListRow with AdwActionRow directly would
end up being more code.
The Screen Sharing dialog used to have a switch, which was changed to a
checkbox in 8b68961431
However, unlike switches, checkboxes are expected to have clicable labels
Let's set the label properly, instead of doing it the switch way.
Fixes https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/565
Put the widget's content into a HdyColumn, itself into a
GtkScrolledWindow. This allows the panel to reach narrower sizes.
This deliberately doesn't adapt the indentation of the contained widget
to help this commit to be more readable and easier to review, it will be
adapted in the next commit.
