Abstract script compiled module implementation used in saving/caching

removes classloading problem when main-kts is loaded from a CL
without scripting compiler.
Also relax dependencies collection on saving to a jar and hide redundant
logging.
Running main.kts script via a run configuration works now.
#KT-37765 fixed
