The kotlin-scripting-compiler-impl jar is used in the idea plugin and
therefore should not depend on the cli parts of the compiler to avoid
dependency from the plugin to the kotlin-compiler.jar.
Therefore the cli-dependent parts were moved to the scripting plugin
jar, which is used only in cli compiler based environments.
Also implement required abstractions to allow this movement and
drop some redundant dependencies to the cli parts in other projects.
