Mention amdgpu-device-libs for allocator and println support and mention the necessary target flag for GPUs from some some series without xnack support.

For the last half year, there were no major changes in the amdgpu-device-libs crate (in fact, there was no need to update the crate), so I believe it is stable enough to mention it here.

The xnack-support flag is something I stumbled upon recently, when more complex printlns failed on a certain GPU.

Tracking issue: #135024
