Fix T65076: Missing EasingType implementation on the Dopesheet

EasingType was implemented rBdaccaa713b6e for the GraphEditor (but never
made it to the Dopesheet). If you can select Easing Mode in the
DopeSheet, then you should also be able to select the associated Easing
Type.

Thanks @lichtwerk for the initial implementation.
