ui: %horizontal-kv-list CSS component (and related) (#10285)
This commit uses docfy to isolate the individual parts and options and investigates the why you might use certain options and document how you might use certain options.

Originally we used a single %icon-definition CSS component to represent this, but seeing as some of them don't have icons, it didn't seem like the best name. So this PR splits this component into various different ones and then uses the new ones to continue to provide a now deprecated %icon-definition.

The component is currently a CSS only component that assumes a single (or multiple) description lists for its markup component, and provides for multiple different options (including a reversed mode which I'm still not totally sure about, but we don't use this right now anyway).

# horizontal-kv-list

Provides a horizontally stacked list of key/value pairs, commonly used with a
definition/description list.

The keys can be configured to be either, visible, invisible, or with an icon.

- **Icon Configuration:** Add a `class` that describes the key/value pair and configure the icon for that class in the CSS
- **Visible Title Configuration:** Add an empty `class` attribute. A trailing `:`
  will be added to the title (ensure you collapse the whitespace in the `dt`).
- **Invisible Title Configuration:** Don't add a `class` attribute at all, i.e. by default
  the title is not shown.

If you are providing an icon, you should also use the `{{tooltip}}` modifier
to provide a textual tooltip for the icon. Using the `{{tooltip}}` modifier
with no arguments will make it use the text/DOM content of the DOM element it
is attached to, see below for a full usage example.

`<CopyButton />` components are commonly added to the value, and can be added
to the left or right of the value.

When conditionally listing key/values within a single `dl`, be aware that if no key/values should be shown, then you will be left with an empty `dl`. If you collapse the whitespace using handlebars whitespace collapsing `~`, then this empty `dl` will be removed from the flow via CSS. Alternatively consider using multiple `dl`s which can be wrapped with conditionals individually and therefore leave no empty DOM.

When using as individual `dl` lists be aware of whitespace between `dl`s. There are various ways you can counter this:

1. remove the whitespace `</dl><dl>`.
2. Wrap the whitespace in comments `</dl><!-- carriage return --><dl>`
3. Use handlebars whitespace removal `~` as above.
4. Put a `display: inline-flex` on the parent element (this can affect other layout).

Depending on your exact usecase one of the above options may be more suited than others.

```hbs preview-template
<figure>
  <figcaption>
    Conditionally showing multiple key/values sometimes means that you insert an empty `dl` into the DOM
  </figcaption>

  <dl>
    {{~#if false}}
      <dt>Something that might not be set</dt>
      <dd>No value!</dd>
    {{/if~}}
    {{~#if false}}
      <dt>Something that might not be set</dt>
      <dd>No value!</dd>
    {{/if~}}
  </dl>
</figure>
```
