[KAPT] KT-65399 Fix rendering of types with names starting with $.

Solves a specific issue with Kotlin serialization, and most likely,
similar issues with synthetic classes.

Types with `$` in other positions will be still rendered incorrectly
due to imprecise conversion of such types from Kotlin to Java
in the analysis API.
