Tree widget: Add option to disable grey highlight and tooltip for touchscreen devices

[JoanaSmit]

• The eye icon is highlighted, and a tooltip appears when hovering on the icon:

• Hover actions do not work properly on touchscreen devices:
  • The eye icon remains highlighted after clicking it, until we click outside the icon
  • Tooltip is blinking
  • Recording
• tree-widget-react version 3.14.0

iTwin/iTwinUI#2631

@JoanaSmit, can you check if bumping iTwinUI version actually fixes the hover effect problem for you (as described by Mayank in the discussion)?

As @saskliutas later clarified, iTwinUI only addressed this in the TreeNode, not in the Checkbox. So bumping iTwinUI will not have an effect.

Tooltip and highlight appear with the latest iTwinUI version
