ui: Exposes the <ToggleButton /> 'click' action (#7479)

This exposes an api for <ToggleButton /> so you can call it from
elsewhere, specifically here we use the api.click to close the dropdown
menus which is required is the DOM containing the toggle button isn't
redrawn as is the case with external links in a dropdown menu

+## ToggleButton
+
+`<ToggleButton checked="checked" @onchange={{action 'change'}} as |api|>Toggle</ToggleButton>`
+
+`<ToggleButton />` is a straightforward combination of a `<label>` and `<input type="checkbox" />` to allow you to easily setup CSS based (`input:checked ~ *`) visual toggling. The body of the component ends up inside the `<label>`.
+
+Additionally, a `clickoutside` is currently included, so if the toggle is in an 'on' state, clicking outside the `<ToggleButton>` itself will un-toggle the component. This could be changed in a future version for this to be configurable/preventable and/or use/rely on a modifer instead.
+
+### Arguments
+
+| Argument/Attribute | Type | Default | Description |
+| --- | --- | --- | --- |
+| `checked` | `Boolean` | false | The default value of the toggle on/off (true/false) |
+| `onchange` | `Function` |  | The action to fire when the data changes. Emits an Event-like object with a `target` that is a reference to the underlying standard DOM input element. |
+
+### Methods/Actions/api
+
+| Method/Action |  Description |
+| --- | --- | --- | --- |
+| `click` | Fire a click event on the ToggleButton/input which reverse the state of the toggle. |
+
+### Example
+
+Here is an example of a simple CSS based dropdown menu. Note: The general sibling selector (`~`) should be used as the label/button itself is the adjacent sibling (`+`).
+
+```handlebars
+<div class="menu">
+  <ToggleButton>
+	  Open Menu
+  </ToggleButton>
+  <ul>
+    <li><a href="">Link 1</a></li>
+    <li><a href="">Link 2</a></li>
+  </ul>
+</div>
+```
+
+```css
+.menu input ~ ul {
+  display: none;
+}
+.menu input:checked ~ ul {
+  display: block;
+}
+```
