Extend the single eager init of HSA queues and move their management into the
AMDGPUStreamManager of an AMDGPUDevice.
Allow a stream to use different HSA queues during its lifetime and identify
busy queues.

When a Stream is requested from the resource manager, it will search for and
try to assign an idle queue. During the search for an idle queue the manager
may initialize more queues, up to the set maximum (default: 4).
When no idle queue could be found: resort to round robin selection.
