Switch apex to Graal javascript engine

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.
