Cleanup imports and minor API tweaks

Remove and reorder unused imports across modules, tidy test import ordering, and apply small API tweaks. Notable changes: remove ListUtils.newLinkedList (and its Javadoc), switch Converters cache value type from ArrayList to List, adjust annotation meta imports (Nonnull/Nullable/ThreadSafe/NotThreadSafe), and other minor import/whitespace cleanups in annotation-processor, java-core, java-annotations and tests.
