Move IC from Gradle to compiler

Reasons for moving:
1. Integration with Kotlin daemon for Gradle.
Gradle bundles Kotlin compiler (kotlin-compiler-embeddable) since Gradle 3.2.
There is no plugin isolation in Gradle, so strange compilation errors/exceptions may happen.
We decided to fix this problem by compiling out-of-process using Kotlin daemon.

Reasons for moving IC to the compiler:
* Better isolation from Gradle process.
* Incremental compilation logic is not scattered across two process and multiple modules.
* Makes it possible to implement standalone CLI IC
