When a policy is loaded, a separate thread is spawned for each
Javascript script executor. This allows us to precompile the Javascript
scripts and also to have a larger stack available for script execution.

Integation unit tests resultd in StackOverflowException errors in the
Graal Javascript interpreter. Following extensive testing and
trouobleshooting, it proved very difficult to fix these issues in Graal
as the stck overflow errors were occurring in native class instantiation
methods being invoked by Grall on the JVM.
The alternative Rhino Javascript engine is developed by mozilla, and was
incorporated into the Java 6 JVM and evolved into Nashorn in the Java 8
JVM. Oracle dropped Nashorn in Java 11. However, in parallel, Rhino
development has continued.
This review brings in the Rhino javascript engine into apex-pdp as the
replacement for Nashorn and instead of Graal. Graal seems to be pretty
unstable as yet so we may bring it in in future releases but for now
Rhino is a more stable and reliable alternative.

This is the main review to switch out the Nashorn Javascript interpreter
and switch in the Graal javascript interpreter for apex Javascript
tasks.
The Graal Javascript dialect differs slightly from Nashorn in the way it
accesses information passed over from the Java world so Javascript
tasks need to be converted.
Subsequent reviews will convert the JUnit tests marked @Ignore in
previous reviews to this one and will convert the Javascript tasks into
a format Graal can handle. Subsequent reviews will also convert the
examples over to Graal format.
