RFR: 8181775: JavaFX WebView does not calculate border-radius properly [v4]

[Bhawesh Choudhary]

> root cause of issue is prism's fillRoundedRect() API doesn't allow rendering of rounded corner rectangle if four
> corners have different radii. but same can be achieved via Path. to fix the issue, in GraphicsContextJava.cpp while
> rendering fillRoundedRect, check if all four corners have same radii. if yes, use FILL_ROUNDED_RECT to draw it
> otherwise construct a path from given rounded rect and draw it.
