build: Switch Kotlin compiler downloading to kotlin-dev bintray repo

This patch uses kotlin-dev bintray repo (dl.bintray.com/kotlin/kotlin
-dev/org/jetbrains/kotlin/kotlin-compiler/) for Kotlin compiler
downloading instead of the sonatype repo and our bintray mirror of it.
So there is not need to run ./gradlew update_kotlin_compiler on each
compiler update.

It also updates kotlin-compiler to 1.1.3-dev-1619
