Target Orbit panel needs a `visibleProperty`

[arouinfar]

Discovered while creating examples.md for #223

There isn't currently a way for clients to hide the target orbit feature. The Target Orbit Panel needs a visibleProperty that is client-controllable. A potentially complicating factor is that the sim needs to control the visibility on the All Laws screen because the panel is only relevant to the first and third laws.

@AgustinVallejo or @pixelzoom please create view.panels.rightPanels.targetOrbitPanel.visibleProperty and make it phetioFeatured: true.

@AgustinVallejo I think the patch below will address this, but I don't have time to test it and will be out tomorrow.

Added this. It had to be a linked property since there's already a dependency with the isSecondLawProperty (so the panel doesn't show up when 2nd law is set). Is this behavior ok @arouinfar? If so, please close

Thanks @AgustinVallejo. The general structure looks good on main, but we'll also need to feature targetOrbitPanel so that the linked visibleProperty shows up in the featured tree.

Done, assigning back

Looks good on main, thanks! Closing.
