Bug - Dropdown/Select/MenuContainer - tooltips do not work by default in items

[kmcfaul]

Because Tooltip wraps the trigger in a div, this interferes with the trigger/hover conditions so a tooltip will not appear. We should make it so Dropdown (and probably Select/MenuContainer will need this as well) creates an internal ref to use by default for tooltips, or we should make it so Tooltip does that internally.

Workaround: Create a reference, pass the ref to DropdownItem and the triggerRef field of tooltipProps.

Aside: Keyboard navigation still shows the tooltip, it is only the mouse that doesn't trigger it.

@nicolethoen, can we get this prioritized so the tooltips in the console masthead can be added back?
