Integrate LiveKit Capture

[ladvoc]

Integrate the new LiveKit Capture crate, allowing the user to publish test tracks using pattern source (logo/gradient) and clock source. This replaces the existing logo track implementation. UI screenshot:

Additional source types will be exposed (e.g., device) as they are available upstream.

Looks good.

I added more descriptive naming and checkboxes to make unpublishing more obvious.

Also the CI was red because of the need for a clang bump and unpublishing was not possible for the sine wave.

Please have a look if you are fine with these commits.

Also I thought about moving the mic input also to the menu as: Audio: Microphone as it is also a track you can publish.

@MaxHeimbrock, changes look good! I think it would make sense to also move microphone to the menu. Once device support in LiveKit Capture is upstreamed, there will be a new option in the menu to publish webcam.

One idea I had is to make this a submenu to allow selecting a specific device:

Publish
└── Video: Camera
    ├── MacBook Pro Camera
    └── HD Pro Webcam

Same could be done for microphone selection.

Yes, I also thought about submenus, like

─ Audio
    └─ Microphone
    └─ Sine Wave
─ Video
    └─ Clock
    └─ Logo
    └─ Camera
        └─ MacBook Pro Camera
        └─ HD Pro Webcam

I am out for a week, so I let you decide if you want to merge this first or continue working on the UI.

Ready to be merged.
