`KSValueArgument.value` may return `List<*>`

The API specifies that `KSValueArgument.value` returns an `Array` of the above listed types, however, if an annotation is given in a Java file as `@Anno(args = [arg1, arg2, ...])`, then `[arg1, arg2, ...]` is returned as a `java.util.ArrayList<*>`. Thus, if you match on the result of `KSValueArgument.value` and match on any or all of the types declared in the documentation, there is a case where the match is non-exhaustive or rather where you never hit a valid branch.

The fix is to check for the `ArrayList<*>` type and convert it to a `kotlin.Array<*>` type.

Start with api/src/main/kotlin/com/google/devtools/ksp/symbol/KSValueArgument.kt around line 55 and reproduce the Java annotation case described in the issue. Trace where the list-valued argument is produced, then verify that the result is exposed as a Kotlin Array so matching against the documented types is exhaustive.
