[ty] Exclude test-related symbols from non-first-party packages in auto-import completions This reduces noise when typing, as test code from dependencies is almost never useful to import. Note that first-party code is never filtered, so that users can still import from their own test modules. Top-level "testing" modules like `pandas.testing` are preserved since they provide utilities meant for external use. Closes astral-sh/ty#2466
