The class is very useful for triaging complex SDMA issues.

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.

Clean up the KFDTest style via CPPLint. Some warnings remain regarding
volatile variables being cast to void*. This is the command used:
cpplint.py --linelength=120
--filter=-readability/multiline_string,-readability/todo,-build/include,-runtime/references
multiline_string is due to using ISA code
todo is to avoid errors that we don't have TODO(username) instead of TODO
include is about including the folder in the header includes
references is regarding non-const references '&' being const or using
pointers. That can be addressed later

Implement sDMA copy packet broadcast.
Each time sDMA will copy its local vram to sysbuf and next GPU's vram.
That will verify where the p2p link is broken.
Currently we just test push of p2p.
test result on 2 cpus, 4 gpus, numa enabled system.
[ RUN ] KFDQMTest.P2PTest
[ ] Test 2 -> 3
[ ] PASS 2 -> 3
[ ] Test 3 -> 4
[ ] PASS 3 -> 4
[ ] Test 4 -> 5
[ ] PASS 4 -> 5
[ ] Test 5 -> 0
[ ] PASS 5 -> 0
[ OK ] KFDQMTest.P2PTest (190 ms)
