[Rev 01] RFR: 8242861: Update ImagePattern to apply SVG pattern transforms

[Arun Joseph]

> fillPath() and fillRect() functions in
> [GraphicsContextJava.cpp](https://github.com/openjdk/jfx/blob/master/modules/javafx.web/src/main/native/Source/WebCore/platform/graphics/java/GraphicsContextJava.cpp)
> use Image::drawPattern() for applying patterns as fill. But drawPattern() doesn't use patternTransform argument as
> ImagePattern doesn't have the same attribute. So, the final image won't be transformed.
