chore: Adds disable dismiss auto-focis for internal chart tooltip

[pan-kot]

Description

This change is required to support cloudscape-design/chart-components#217, where the use case requires the dismiss button to appear, while the focus stays on the legend item - this is different from the conventional popover use with click activation or charts use, where the tooltip does not have a dismiss button unless pinned.
