RFR: JDK-8325841 - Remove unused references to newInstance0

Thu May 23 21:55:08 UTC 2024

Can I please get some reviews for this change to remove unused names from `vmSymbols.hpp`?

As far as I can tell there is nothing in the code base using these symbols. My search was just a simple grep + some bash script, though. I tested using JTREG on MacOS, Linux Mariner & Alpine from tier1 to 3.
