oneAPI / SYCL Image Updates, master branch (2024.05.30.)

[krasznaa]

Simplified the SYCL build flags for AMD and NVIDIA backends.

The main motivation was to change the setup of the AMD backend. Since as it turns out, traccc cannot be compiled for the gfx803 architecture (which is what my personal RX580 card has...) anymore. 🤔 One gets such a scary crash with it during linking:

LLVM ERROR: failed to find free scratch register
PLEASE submit a bug report to https://software.intel.com/en-us/support/priority-support and include the crash backtrace.

After playing around for a bit, I found that the gfx1031 architecture (used by our developer machine's RX6700XT card...) still works,

But as long as I was already doing this, I also simplified the images to only build SYCL code for AMD / NVIDIA backends respectably. Since building traccc::sycl for both Intel + AMD/NVIDIA backends takes a ridiculous amount of time. Not to mention that it's also pretty fragile.

Pinging @andiwand for info. 😉
