bug(drag-drop): `Point` interface is not exported in the public API

[Achilles1515]

Issue

The Point interface:

/** Point on the page or within an element. */
export interface Point {
  x: number;
  y: number;
}

is defined and exported inside drag-ref.ts. This interface is used in the public drag-drop API, e.g.

@Input('cdkDragConstrainPosition')
constrainPosition: (point: Point, dragRef: DragRef) => Point

But Point is missing from the public-api.ts exports.

export {DragRef, DragRefConfig} from './drag-ref';

...should include Point as well.

export {DragRef, DragRefConfig, Point} from './drag-ref';
