Also move jdbc classes to bootstrap to reduce size and complexity of those reference checkers.
These changes reduce the total file size of these instrumentation classes by 635k, which should also result in decent memory savings.
Replacing Advice.class references with string construction.
This stops the JVM from loading the Advice classes which are used as templates for byte buddy and doesn't ever need to be run directly.
This eliminates ~130 class loads at start-up -- and saves 0.5MiB in metaspace
