Add RDNA1 and RDNA2 architecture detection

Add detection functions for RDNA1 and RDNA2 GPU architectures to enable
proper hardware identification and kernel dispatch. This infrastructure
enables subsequent commits to properly distinguish between RDNA generations
and apply appropriate tensor core constraints, as RDNA1/RDNA2 have limited
tensor core capabilities compared to RDNA3/4.
