This blindly changes logging to nim-chronicles - issues that ensue: * keeps gas cost computation logs hidden behind flag * unclear if logScope is practical - for example, since vm is split over many files, topics get lost when using simple top-level per-module topics * when passing named object around, scope should incliude the name of the object but this is caught neither by logScope nor by dynamicLogScope
