Light classes: use JVM target from the module

Using "JVM_1_8" always resulted in incorrect mapping of Kotlin
annotation targets to Java element types.

The change in AbstractKotlinRenderLogTest is needed because while
CliTraceHolder.module is technically a descriptor leak, it was never
detected by this test accidentally, because of the depth cutoff equal to
10, which started to not be enough after the minor refactoring of
replacing `Delegates.notNull` with `lateinit`.
