Declaration-site annotation targets are not respected

KSP does not currently consider the meta annotation `@Target` on declared annotations. For instance, KSP will return a property annotated with an annotation that only targets classes:
```kotlin
@Target(AnnotationTarget.CLASS)
annotation class Anno

// Here we expect KSP to only return Main on Resolver.getSymbolsWithAnnotation("Anno")
// but it returns both Main and Main.annotatedProperty.
@Anno
class Main {
@Anno
val annotatedProperty = 1
}
```
However, considering that this has always been KSP's behavior, is this change something we should even consider? Doing so could break a lot of downstream builds. How do symbol processors deal with this? Is this entirely ignored?

EDIT: This is definitely a bug, but Kotlinc will yield an error, so while KSP may succeed there is not silent failure.
