RFR: 8257512: Remove use of deprecated primitive constructors in JavaFX [v5]

[Ambarish Rapte]

> The following primitive constructors were deprecated in JDK 9 and are deprecated for removal in JDK 16.
> 
> java.lang.Byte
> java.lang.Short
> java.lang.Integer
> java.lang.Long
> java.lang.Float
> java.lang.Double
> java.lang.Character
> java.lang.Boolean
> 
> This change removes call to the primitive constructors with the `valueOf()` factory method of respective class.
> Calls like the following to create array get autoboxed so it does not require a change.
> 
> `Double dArr[] = new Double[] {10.1, 20.2};`
