Update JavaDoc in javafx.geometry.Point3D

A DESCRIPTION OF THE PROBLEM :
The method equals() JavaDoc describes the method as hashCode(). It is a copy/paste error.
I have proposed a simple JavaDoc for Point3D.equals(), BASED ON THE EXISTING JAVADOC FOR java.awt.Point.equals()

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Browse to https://docs.oracle.com/javase/8/javafx/api/javafx/geometry/Point3D.html#equals-java.lang.Object-


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Doc describes the equals method
ACTUAL -
Doc describes the hashCode method

FREQUENCY : always
