[KSP2] NPE when getting annotation arguments on non-Jvm targets

[DennisTsar]

Calling KSAnnotation.arguments for an annotation with arguments fails with KSP2 on non-Jvm targets with the following error:

java.lang.NullPointerException: null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl
	at com.google.devtools.ksp.impl.symbol.kotlin.UtilKt.getDefaultValue(util.kt:430)

This seems similar to #1798 , but does not involve Java in any way.

This likely requires an upstream fix for metadata for klib.

Any timeline for this bug fix?

The dependent upstream issue is targeting Kotlin 2.1, we will likely have to wait until then.
