Subject: [PATCH] [Native][tests] Add standalone test for KClass package names

To ensure that after introducing `ReflectionPackageName` annotation,
we still have tests that check KClass package names without it.

+// TARGET_BACKEND: NATIVE
+// NATIVE_STANDALONE
+
+// Purpose of this test is to check that Kotlin/Native still generates correct
+// package names in reflection information without package patching.
+//
+// Native test engine by default groups tests to single compilation, and
+// renames packages to avoid clashes.
+// To make reflection-related tests work, it inserts ReflectionPackageName
+// annotations when patching, to instruct the compiler to use the original
+// package name for reflection information.
+//
+// The NATIVE_STANDALONE directive above disables test grouping.
+// So this test basically checks that without ReflectionPackageName the compiler
+// can still properly handle reflection information for classes and generates
+// correct package names.
