[impact-analysis] support declared types

[tkobayas]

Issue

Support declared types.

For example

package org.example;

global java.util.Set controlSet;

declare DeclaredInDrl
    name : String
end

rule "will execute per each Measurement having ID color"
when
    Measurement( id == "color", $colorVal : val )
then
    controlSet.add($colorVal);
    System.out.println("Test " + $colorVal);
    DeclaredInDrl test = new DeclaredInDrl();
    test.setName("test");
    insert(test);
end

Fails with

ava.lang.RuntimeException: java.lang.ClassNotFoundException: Unable to find class 'DeclaredInDrl'
