tests,gpu-compute,mem-ruby: Add GPU Ruby random test
This adds the GPU protocol random tester to the quick/Kokoro tests. The
input has been sized to take around 20 seconds and provides good
coverage for the coherence protocol.
This test can be run with the following:
```
cd tests
./main.py run -j`nproc` gem5/gpu
```

+This test will first run the GPU protocol random tester -- it should take
about
+30 seconds to run and provides good coverage for the coherence protocol.
+
+Input choices (some are default and thus implicit):
+ - use small cache size to encourage races
+ - use small system size to encourage races since more requests per CU (and
+ faster sim)
+ - use small address range to encourage more races
+ - use small episode length to encourage more races
+ - 50K tests runs in ~30 seconds with reasonably good coverage
+ - num-dmas = 0 because VIPER doesn't support partial cache line writes,
which
+ DMAs need
