kfdtest: add KFDTestUtilQueue

Some infrastructures below,
Implement SdmaTimePacket which records the global GPU timestamp.

Introduce class AsyncMPSQ and AsyncMPMQ.
AsyncMPSQ is aka async multiple packet single queue. It takes a set of
packet when create and submits them to a GPU to run. While AsyncMPMQ is
aka async multiple packet multiple queue. It manages a set of AsyncMPSQ,
and use a forloop to do operations of AsyncMPSQ.

Implement sdma_multicopy helper functions.
