There are many other places where we print addresses, for instance a in `LayoutPath`, when slicing a segment, or when reading an address with a layout from a segment to name a few. We should fix all of them so that we don't create an inconsistent way of printing addresses.

There are also cases which are not present in mainline, like the UOE throw from VarHandleSegmentViewBase: https://github.com/openjdk/panama-foreign/blob/cbaf7084417a2f87ddf7a8721893931d02416271/src/java.base/share/classes/java/lang/invoke/VarHandleSegmentViewBase.java#L61

I think it might be better to fix this in the panama-foreign repo, and then move over to this repo after the JEP for 22 is integrated (which contains some of the new code).
