Rotate a given point by a given angle around the origin (0, 0), in an anti-clockwise direction.

@function Phaser.Math.Rotate
@since 3.0.0

@param {(Phaser.Geom.Point|object)} point - The point to be rotated.
@param {number} angle - The angle to be rotated by in an anticlockwise direction.

@return {Phaser.Geom.Point} The given point, rotated by the given angle in an anticlockwise direction.
