RFR: 8210807: Printing a JTable with a JScrollPane prints table without rows populated

`BackingStore` uses its own Graphics to Paint the Image. This is fine when we want to paint it on a Window/Frame, but fails to print. Since `WPathGraphics` is used for Printing, backing store fails to print it and backing store uses newly created `SunGraphics2D` always. The proposed fix is to ignore `backingstore` graphics if passed on Graphics is different from `SunGraphics2D` which ensures the Image is painted on Window and also printed when required. 
The fix is tested in CI and doesn't cause any regression. The test is verified manually.
