Create KFDTest for SDMA Fault

The purpose of this KFDTest is to investigate the behaviour of an
SDMA queue when an invalid memory address is used.

v2: Don't wait for SDMA queue to finish - it won't finish because of
the gpuvm fault.

v3: Create kfd event before SDMA queue submission. This fix the issue
that gpuvm fault happens earlier than kfd event is created then KFD
exception handler can't find the kfd event (to wake up kfd test)

v4: Instead of using 0x12345678 as the invalid VA, map one page of
FB to gpu and unmap it. Use the mapped GPUVA as the
invalid address
