[jdk17u-dev] RFR: 8294680: Refactor scaled border rendering

[Goetz Lindenmaier]

I backport this to make later backports more simple. 
We should keep 17 up to date, especially in awt/javax where
subtle bugs can annoy users.

I had to resolve SwingUtilities3.java as two later changes were already backported,
see History of [17](https://github.com/openjdk/jdk17u-dev/commits/master/src/java.desktop/share/classes/com/sun/java/swing/SwingUtilities3.java)  compared to [21](https://github.com/openjdk/jdk21u-dev/commits/master/src/java.desktop/share/classes/com/sun/java/swing/SwingUtilities3.java)

The file is now at the level of 21, except for  [8285306: Fix typos in java.desktop](https://github.com/openjdk/jdk21u-dev/commit/2a799e5c82395919b807561da4a062e0fe6da31d)
