8368977: Provide clear naming for AVX10 identifiers

[missa-prime]

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 as the baseline build.

LGTM, naming now follows the AVX10 versions sheme where an instruction supported by a version is guaranteed to be supported by all the version above it.

@eme64, @mhaessig Ok to test?

@iwanowww In case you want to glance through changes.
