RFR: 6899304 : java.awt.Toolkit.getScreenInsets(GraphicsConfiguration) returns incorrect values [v6]

[anass baya]

> Screen number 0 is not always the primary screen, so we’ve removed the code that assumes it is.
> 
> We used an existing test and took the following considerations into account for Windows:
> 
> - On Windows, undecorated maximized frames are placed over the taskbar.
> - On Windows, the top-left corner of an undecorated maximized frame may have negative coordinates (x, y).
> - Consider the fractional part after scaling.
