kfdtest: increase KFDPerformanceTest.P2PBandWidthTest timeout value

KFDPerformanceTest.P2PBandWidthTest[push, push] takes about 3 seconds
on 4 gfx906, the default g_TestTimeout 2 seconds is not enough to wait
for sDMA queue rptr is consumed. Use kfdtest command line option
--timeout=6000, the test is finished and result is reasonable twice as
P2PBandWidthTest[push, none]. Change P2PBandWidthTest wait timeout to 6
seconds.

Add timeout argument to function WaitOnValue, BaseQueue.Wait4PacketConsumption
SDMAQueue.Wait4PacketConsumption, PM4Queue.Wait4PacketConsumption with
default value is g_TestTimeOut.
