Subject: [PATCH] Introduce internal property sourceMapBaseDirs for
 Kotlin2JsCompile

Separate property needed to prevent Gradle snapshotting absolute paths
as inputs when passed as compiler argument.
To reduce property visibility to external users put it to the impl class
which will make it invisible in completion but still usable in Kotlin
build.
