[TASK] Resident Eval - The Removal from FormEngine

A long long time ago jsfunc.evalfield.js found its way into the core.
Now - after 12 years - it is time to leave.

This patch removes the usage of jsfunc.evalfield.js from FormEngine
and moves the logic into FormEngineValidation.js as a first step.
The validators and processors have been split up into two methods.
