resources: Update square for ROCm 4 and dGPU support

ROCm 4 made it so previous methods of GPU memory management
used in ROCm 1.6 don't work in gem5. To get around that, we
use hipHostMalloc, which allocates host and device accessible
memory at the same time, all in a single pointer.

Additionally, because APU and dGPU code now don't allocate
memory differently, the #DGPU define is removed.

Finally, the Makefile is updated to build all supported GPU
versions into the same binary.
