Existing QUEUE_TYPE_SDMA means PCIe optimized SDMA queues.
Introduce a new QUEUE_TYPE_SDMA_XGMI, which is optimized
for non-PCIe transfer such as XGMI.

MEC FW for some new asic requires all SDMA MQDs to be in a continuous
trunk of memory right after HIQ MQD. Add a field in device queue manager
to hold the HIQ/SDMA MQD memory object and allocate MQD trunk on device
queue manager initialization.

Previously mqd managers was initialized on demand. As there
are only a few type of mqd managers, the on demand initialization
doesn't save too much memory. Initialize them on device
queue initialization instead and delete the get_mqd_manager
interface. This makes codes more organized for future changes.

Wavefront context save data is of interest to userspace clients for
debugging static wavefront state. The MQD contains two parameters
required to parse the control stack and the control stack itself
is kept in the MQD from gfx9 onwards.

Add an ioctl to fetch the context save area and control stack offsets
and to copy the control stack to a userspace address if it is kept in
the MQD.
