[plasma/aurorae/Plasma/6.7] v2: v2: Visualize checked state

Git commit 81e7de9fc7099d44d8531519c6766cf351bec6ed by Vlad Zahorodnii.

v2: Visualize checked state

The checked state is used by buttons such as "on all desktops". When a
window is placed on all desktops, the on all desktops button will enter
the checked state. It will be useful if the on all desktops button
communicates that state.

The maximize button is rather special because it uses a different svg to
represent the checked (maximized) state. In hindsight, we should have
had the "checked" element prefix. That way we could combine checked +
pressed.
