refactor: remove ui5-toolbar (#198)

Remove the ui5-toolbar and all affected files and replace it with div element everywhere it is used, including panel and list samples.

BREAKING CHANGE: the ui5-toolbar component is removed, we recommend using div or similar HTML tag in combination with flex instead.
