fix: Allow hover tooltips to be dismissed using Esc

[avinashbot]

Description

Does what it says on the tin - tooltips should be dismissible by hitting the Escape key. I know the visibility logic for the tooltips is handled outside them, but it still seemed sensible to put the dismiss handler inside the tooltip in one shared place.

How has this been tested?

Added a unit test to the tooltip component itself, and all other components just implement it as a callback on the tooltip, so I didn't feel more testing was needed. Might add tests to select/multiselect though.
