RFR: 8376186: [VectorAPI] Nomenclature change for concrete vector classes

[Jatin Bhateja]

As per https://github.com/openjdk/jdk/pull/28002#issuecomment-3789507594 on JDK-8370691 pull request, splitting out portion of PR#28002 into a separate patch.

In preparation of Float16 vector API support, changes to nomenclature of concrete vector class by suffixing the vector type with vector bit sizes e.g. FloatVector256 so that we don't end up generating names like Float16256Vector.

All existing Vector API jtreg test are passing with the patch.

Kindly review and share your feedback.

Best Regards,
Jatin
