Configuration checkbox to hide unavailable profiles
pavucontrol shows all device profiles by default: (unplugged) and (unavailable). This takes up a lot of screen real-estate on smaller displays. This PR adds a checkbox for showing/hiding the aforementioned device profiles. The profile dropdown box ends up being a lot more cleaner and easy to find the relevant profile as a result.
The checkbox state defaults to checked to preserve original behavior of showing all available profiles by default.
