Bump minimum JDK distribution version needed for builds to 24

Updating minimum JDK build version to 24, it contains new two vector selectFrom API[1] which can be used to build wider lookup table[2] optimize StructuralIndexer and Utf8Validator. In addition I am also planning to optimize exsting ByteVector shuffling in Utf8Validator using Vector.slice API as per the proposal on panam-dev mailing list[3] Following are JMH micro profiles with JDK24 and earlier version of JDK18.
