Removed name-based matching of source/javadoc artifacts to jar artifacts in IDE plugins

- It was decided that the IDE plugins isn’t the correct place for logic that binds
  jar artifacts to source artifacts. Instead this should be done as part of
  component modelling in dependency resolution.
- The `eclipse` plugin continues to bind a single source/javadoc artifact 
  to each jar entry.
- The `idea` plugin binds all available source/javadoc artifacts to each jar entry.
