Adds UUI-Copy

[warrenbuckley]

Description

Adds a button to trigger copying content to the clipboard, by two approaches:

• Setting the value property on uui-copy to contain the text content you want to copy to the clipboard
• Setting the copy-from property will look for HTML element with that ID and use the text content
  • If the selected element has a value property then assume we want to get the value of an input field such as uui-input
  • By setting copy-from it overrides any value set in the value property

Note

This is heavily inspired by Shoelace.style copy button
https://github.com/shoelace-style/shoelace/blob/next/src/components/copy-button/copy-button.component.ts
