Add benchmarking for Jackson Blackbird

[darxriggs]

Blackbird will eventually replace Afterburner.

see https://github.com/FasterXML/jackson-modules-base/tree/2.13/blackbird

NOTE: When running this on Java <9, the following warning is logged (incl. a stacktrace).

com.fasterxml.jackson.module.blackbird.util.ReflectionHack$Java9Up init WARNING: Unable to find Java 9+ MethodHandles.privateLookupIn. Blackbird is not performing optimally! java.lang.NoSuchMethodException: no such method: java.lang.invoke.MethodHandles.privateLookupIn(Class,Lookup)Lookup/invokeStatic

The code change LGTM

Please run the ser+deser benchmark with jackson blackbird (and another lib – "normal" jackson itself is fine) for both user and client objects and post the results here.

For Java 8 the performance is similar to not using Blackbird.

For Java 17 (where -XX:+AggressiveOpts is not available anymore) the optimization is more visible.

But all in all the variance between different runs is pretty big so comparisons are difficult.
