>> This is a simple change that renames all AVX10 identifiers to explicitly show which sub-versions are in use. Right now, AVX10.2 is the only case to worry about. The JTREG tests listed below were used to verify correctness with the recommended JVM options mentioned in corresponding source files. Each test included runs through emulation with AVX10.2 enabled and disabled to exercise all possible paths. All modifications and tests used [OpenJDK v26-b24](https://github.com/openjdk/jdk/releases/tag/jdk-26%2B24) as the baseline build.
