Annotation with `Class[]` member always returns an empty list

[ZacSweers]

I've been trying to write a prototype of AutoService via KSP, and notice that the value field (a Class array) always returns an empty list when I try to query the annotation value in KSP

Repro branch: https://github.com/ZacSweers/moshi-sealed/tree/z/ksp

Under AutoServiceKsProcessor.kt, there's a println with a comment where it finds an empty list

A PR to this and #71 is on the way: android/kotlin#29

The empty list here is actually a symptom of the failure to resolve SymbolProcessor in the annotation.
