KMA-413 Publish AC KMM's backend.native dependency with Kotlin-for-IDE

AppCode KMM uses parts of `backend.native` for its Kotlin-ObjC
cross-resolve. Thus, this IDE dependency needs to be kept up-to-date
with the other Kotlin compiler for IDE artifacts. This commit integrates
a stripped down version into the existing `ide-plugin-dependencies`
build infrastructure to make it easier to keep them in sync.

Implementation details:
* Proguard-based removal of code irrelevant for IDE for smaller jar size
* Publication of non-stripped-down sources for better IDE experience
