Change how kotlinc and tools display their version

- Display the Kotlin version in kotlin-gradle-plugin. This is needed
  because if "-version" is specified in compiler arguments, the "info"
  level of the message printed by the compiler in CLICompiler prevents
  it from being displayed by default (unless "--debug" is passed to
  Gradle).
- Display the version of JRE the compiler is running on. This will be
  helpful to diagnose Java 9 related issues in the future.
- In CLI, also display the executable name (kotlinc-jvm or kotlinc-js)
