Meaningful semantic change was splitted into 5 commits to simplify the
change review. Sinle commit would be too big.
Why replace source to binary: to get rid of kotlin-reflect in Kotlin
plugin artifact KTIJ-22276
Note: Kotlin Maven artifacts (./gradlew publish) changed their
dependency on kotlin-reflect
Review: https://jetbrains.team/p/kt/reviews/6753
Why: I'm going to replace source dependency on kotlin-reflect with
binary dependency. Normalize reflect dependency before global
processing.
This is needed to provide ability for declaring new implementations of
test generators, based on existing infrastructure, which won't add
dependency on :compiler:tests-common
Also this commit removes implicit dependency on :compiler:tests-common
from :compiler:tests-common-new
When plugins DSL is used, there is no need to
manually generate typesafe accessors for extensions and
conventions (by running `./gradlew kotlinDslAccessorsSnapshot`).
