We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
If it isn't ANNOTATION_CLASS, the newly added code in
`FunctionCodegen.isDeprecatedHidden` (0e91d3fcb0) ends up transforming
IR annotation constructor calls to annotation descriptors, and an
assertion fails in `IrBasedDeclarationDescriptor.toAnnotationDescriptor`
which checks that the class has kind ANNOTATION_CLASS.
Specifically, this failed in the JVM IR bootstrap on
`CallResolutionInterceptorExtension.interceptCandidates` from module
'frontend'.
