noCommonMainPlatformDependencies

Forbids a KMP module's commonMain source set from depending on a platform-only (JVM- or Android-only) module - such a dependency does not compile for the module's other targets. Reports kmp-common-main-platform-dependency at ERROR (override with rule("kmp-common-main-platform-dependency") { severity = WARNING }). No-op on projects with no KMP source-set dependencies.
