Modularize test module (#2720)

* Extract KtCompiler to detekt-parser preparing a minimal test utils module

* Fix potential memory leak in tests not closing settings

* Move parsing and generic test utils to own module

* Do not depend on test module for metrics, gradle plugin and generator modules

* Exclude test-utils from coverage report as we do with test module

* Explicitly depend on core-module in tests
