[ByteCodeViewer] IDEA-375559 make Bytecode Viewer work for Kotlin and Groovy sources

Browse Source 
Probably it works for Scala sources too, but I didn't have any sample Scala project at hand
(and have never written a line of Scala).

Previously, the Bytecode Viewer didn't work if triggered for Kotlin, Groovy, or Scala source file
(though it worked if it was invoked on a .class file generated from their sources).

This potentially obsoletes the Kotlin's completely separate implementation of a bytecode viewer,
accessible through the "Show Kotlin Bytecode" action.

Kudos to Nikita Skvortsov for telling me about the CompilerPaths#getOutputPaths method!
