8243009: SwingSet2 scrolling doesn't repaint properly on Catalina

[aghaisas]

Issue : https://bugs.openjdk.java.net/browse/JDK-8243009

Root cause : If the same texture is provided as source and destination with some offset, copyArea function results in texture tearing effect.

Fix : Copy the data from the source texture to a temporary buffer and then copy from that temporary buffer to the destination (source texture with some offset)

Note : This solution may be slower, need to find an optimum way to copy data from MTLTexture to the same texture with some offset.
