Change the UI for switching workspaces to a HTML / CSS one like the rest of the floorp UI

Right now the menu looks very unpleasant, with or without my CSS theme, and its harder to apply CSS to it than if it used the same UI elements as the rest of Firefox / Floorp.

Isn't changing the structure and changing the look of the structure two different things?

@menndouyukkuri I didn't say anything about structure, maybe it's a translation issue on your end? Anyway, I think the menu should look cleaner, like have the workspaces consistently sized, and to have just one button per row instead of two.
