RFR: 8299497: Usage of constructors of primitive wrapper classes should be avoided in java.desktop API docs

[Tingjun Yuan]

API docs of `java.awt.image.renderable.ParameterBlock` and `java.awt.font.LineBreakMeasurer` used deprecated constructors of `java.lang.Short` and `java.lang.Float`.

Replacing by `valueOf` factory methods.
