How do I add the JDK classpath to a compiler configuration? I was calling `configureJdkClasspathRoots()` but it no-ops when the JDK is Java 9+, presumably due to the switch to modules and the disappearance of `rt.jar`. It seems like there's helpers for adding module roots given I know the path. Is it just my responsibility to do the JDK lookup, check for modular, and then conditionally do one or the other?

In CLI mode filling the `CompilerConfiguration` is spread across a lot of different places, and it's hard to find all required places
So I recommend to check <https://github.com/JetBrains/kotlin/blob/d4cffb8a5a113292dfb2a4221a138672994d1c53/compiler/tests-common-new/tests/org/jetbrains/kotlin/test/services/configuration/JvmEnvironmentConfigurator.kt|JvmEnvironmentConfigurator> class, which setups all required fields for configuration in tests (including different JDK) in one place
