Fix on_submitted_work_done_async crash: missing WGPUStringView in callback signature

+### Fixed:
+* `GPUQueue.on_submitted_work_done_async()` no longer raises `TypeError` when
+  building its callback struct. The ffi callback was missing the
+  `WGPUStringView message` argument that the `WGPUQueueWorkDoneCallback` typedef
+  requires, so any call to it crashed. Also un-shadowed the test that covers
+  this path (it was named `make_pipeline_async` so pytest never collected it).
