RFR: 8140527: JInternalFrame has incorrect title button width [v4]

[Prasanta Sadhukhan]

> Title buttons under Widows Classic L&F got their sizes from the XP desktop theme in which button width can be bigger than height. It is construed as XP bug where sizes aren't updated properly so it uses height units for width for XP and later windows. The proposed fix uses the [same technique](https://github.com/openjdk/jdk/blob/a0595761ef35c4eec8cb84326a869b9473cd5bba/src/java.desktop/windows/classes/com/sun/java/swing/plaf/windows/WindowsInternalFrameTitlePane.java#L78-L82) for Classic and forces title buttons to be square and to fit the frame title in height.
