CAMEL-18977: camel-joor - Make the code more flexible for native mode

[essobedo]

Fix for https://issues.apache.org/jira/browse/CAMEL-18977 (for 3.x)

Motivation

With the current code base, it is hard to change the behavior of the jOOR language in order to move most of the logic at build time and/or at static initialization time, without having to use ugly hacks like reflection. The goal of this task is to make the code more flexible to avoid using hacks.

Modifications:

• Add a constructor to the class JoorLanguage to be able to inject specific jOOR compiler and jOOR script compiler
• Add getters for the jOOR compiler and jOOR script compiler
• Make the method evalCode public to give access to the generated code.
