There seems to be no point in configuring the compiler argument per project. This argument will be deleted soon anyway, when we remove support for JDK 1.6 & 1.7. Also remove `disableDeprecatedJvmTargetWarning`. It didn't have any effect in all modules where it was applied because these modules reassign `freeCompilerArgs` anyway, with `-Xsuppress-deprecated-jvm-target-warning` in it.
kotlinx-metadata
This is the platform-agnostic part of the Kotlin Metadata library, intended to provide the possibility to read and modify metadata of Kotlin declarations in the binary (.class, .js) files emitted by the Kotlin compiler. This part of the library is currently not released on its own. Please refer to kotlinx-metadata-jvm for instructions on how to load and modify Kotlin Metadata in JVM binaries (.class and .kotlin_module files).
