[SYCL][CUDA] Matrix MMA for double type using nvptx.

[JackAKirk]

Integration test for the new CUDA MMA implementation using double type for the matrix elements.
See intel/llvm#4696 for the implementation.

Can we use a different prefix in the name like "tensorcore" rather than "nvptx"?
Also, can you add a comment that in the tensor core case, JIT compilation is not supported an specifying the arch argument is necessary?
I know this will be added as part of the doc but repetition can be useful here.

[JackAKirk]

Yeah both suggestions sound good to me.

[JackAKirk]

Made the change

[dkhaldi]

I think a comment is necessary here to highlight the difference with the current matrix interface WRT the use of the "use" argument.

[JackAKirk]

OK

I do not appear to have access to see the pre-ci-cuda report, but it may fail because sm80 architecture is not available. If this is the case could you advice whether it is possible to provide a flag for the unit test so that it only runs if sm80 is available?

Here is the output of the failing test:

Thanks, I reverted the clang-format change. Hopefully it works now.
