Log version in JPS plugin

CompilerVersion.java is moved to cli-common (shared between compiler and JPS plugin) and renamed to KotlinVersion

This is needed because on TeamCity a JPS plugin is configured separately from the compiler, so it may happen that
JPS plugin version X tries to run compiler version X+100, and causes trouble.
