Allow customization for visual appearance of @storybook/addon-themes addon

[soosap]

Is your feature request related to a problem? Please describe.

The visual appearance of this addon is not that nice. All controls in the control panel take up the same amount of space. But for some reason the dark/light toggle can only be rendered with 5x the real estate that is given to other controls.

Describe the solution you'd like

It would be nice if we could configure the visual appearance. I'd prefer something more in the lines of:

In other words, customization should allow to just use:

• "icon-only"
• "icon" + "mode name" i.e. dark, light.
• "icon" + "mode name" + "suffix" i.e. dark theme, light theme OR dark mode, light mode

Also the terms mode and theme are used interchangeably. That is adding a lot of confusion to my project, in which I refer to dark/light as mode and to primary, secondary, danger, etc. as theme. The control hard coding the terms "x-theme" and "y-theme", while theme means something else in my code base is a pain.
