[feat] "Hide" or "Show" Eyeball icon on the layers list

[drfarrell]

Allow users to toggle whether a layer is visible or not in the layers panel.

• Use a Radix eyeball icon to the right of the layers panel.
• When a layer is tucked away inside a parent layer that is hidden, collapse the list of layers and if the layers list is open, make the layer name colors a darker shade of grey.

Hey @drfarrell , and @Kitenite, can I take a crack at this one? It looks pretty straightforward.

[Kitenite]

@katungi, go for it! Don't worry about the actual hide canvas element logic. That can be done in a separate PR

[drfarrell]

@katungi I'm going to open up the issue to other contributors to potentially take on during hacktoberfest – lmk if you'd still like to take it on!

Hi @drfarrell @Kitenite ! I'd love to contribute to this issue as part of hackoberfest.

[Kitenite]

Have at it @RaghavGanesh7 ! I can add the functionality separately once you're done
