8311130: AArch64: Sync SVE related CPU features with VM options

[eastig]

Clean backport of JDK-8311130 which is needed for backports of:

• https://bugs.openjdk.org/browse/JDK-8321025 "Enable Neoverse N1 optimizations for Neoverse V2"
• https://bugs.openjdk.org/browse/JDK-8321105 "Enable UseCryptoPmullForCRC32 for Neoverse V2"

@shipilev, could you please have a look?

I think this is fine, but I would rather like to do stuff in upstream jdk21u and cherry-pick up stuff from there, if possible. Alternatively, can we pick up just the model_is definition for two subsequent backports to work?

Just taking model_is works for me. I am closing this PR.
