Leverage accelerated vector hardware instructions in Vector Search. Lucene already has a mechanism that enables the use of non-final JDK APIs, currently used for the Previewing Pamana Foreign API. This change expands this mechanism to include the Incubating Pamana Vector API. When the jdk.incubator.vector module is present at run time the Panamaized version of the low-level primitives used by Vector Search is enabled. If not present, the default scalar version of these low-level primitives is used (as it was previously). Currently, we're only targeting support for JDK 20. A subsequent PR should evaluate JDK 21. --------- Co-authored-by: Uwe Schindler <uschindler@apache.org> Co-authored-by: Robert Muir <rmuir@apache.org>
