[24] JEP 489: Vector API (Ninth Incubator)

[mpalat]

ref: https://openjdk.org/jeps/489

Summary
Introduce an API to express vector computations that reliably compile at runtime to optimal vector instructions on supported CPU architectures, thus achieving performance superior to equivalent scalar computations.

also, ref: "We propose here to re-incubate the API in JDK 24 with no API changes and no substantial implementation changes relative to JDK 23." -> refer issue #2332
