RFR: 8313139: INTERNAL_VISIBILITY should check for OS

Wed Jul 26 05:05:07 UTC 2023

INTERNAL_VISIBILITY should check for the Operating System we are currently on and should be redefined as specified in the comment if we are on Windows (more OS conditions can be added later).

This change is part of [JDK-8288293](https://bugs.openjdk.org/browse/JDK-8288293), the preliminary phase of which is nearing completion. The changes here are somewhat minimal and hopefully not too disruptive
