Adds simple-copy-button component to fix copying in Safari

What does this MR do and why?

Adds yet another component to render a button that programmatically copies text to the clipboard.

It should fix problems when copying the Runner installation CLI instructions in Safari.

Changelog: fixed

Note: This idea to implement this originally came from !207236, as some of the components we use fail in different situations (non-secure testing environments, modals or Safari).

Slightly Opinionated UX: This implements a copy button that 1) shows a toast when copying is successful 2) hides the tooltip for 3 seconds to avoid flickering when copying.
