Log Message: 
-----------
SDK-20898 - DropDownList dropDown height varies when a horizontal scroll bar is used
SDK-20895 - DropDownList has floating horizontal scroll bar when only one line is present in dropDown
SDK-19879 - Spark DropDownList control with custom TileLayout skin is incorrectly sized and doesnt show all items first time dropdown is opened

Changed the sizing logic in PopUpAnchor so that we only explicitly set the width or height if the respective autoSizePopUpWidth or autoSizePopUpHeight properties are set to true. When either width or height aren’t explicitly set, the popUp will automatically resize that dimension if the measured size has changed. 

Additional Change: 
Added a new spark.core.RelativePosition enum class for the PopUpAnchor.popUpPosition property. Possible values include “left”, “right”, “above”, “below”, “center” and “exact”.
