[Driver][SYCL][NFC] Update test names

[bader]

Add sycl- prefix to the tests checking SYCL mode to make it easier to
find.

Changed file extension from .c to .cpp for libsycl-print-file-name.c
and print-internal-defines-for-sycl.c tests.

@uditagarwal97, what is going on with the Check for private emails used in PRs / validate_email (pull_request)? I'm pretty sure that I use corporate email for my contributions.

That's weird. Let me debug it.

Is it okay to merge with this check failing?

Yes, please feel free to merge. It's a CI issue.

Hi @bader and @mdtoguchi

Sorry. I just saw this. I am just wondering if it would have been cleaner to move all sycl related test to a sub-directory instead of renaming.

Thanks

@asudarsa, do you mean replace clang/test/Driver/sycl-<test-name>.cpp to clang/test/Driver/SYCL/<test-name>.cpp?
I'm okay if we run this through upstream first. Community uses prefixes for CUDA/HIP/OpenMP tests. It would be nice to have consistent scheme.
