Previously, HSA_OVERRIDE_GFX_VERSION=10.3.0 was unconditionally set for
all AMD GPUs, which caused suboptimal performance on RDNA 3/4 GPUs
(gfx11xx/gfx12xx) that have native ROCm support.
Now uses rocminfo to detect all GPUs and only sets the override for
systems where the oldest GPU needs it (RDNA 2 and older, gfx10xx and
below). Newer GPUs are left untouched.
Addresses CodeRabbit review:
- Case-insensitive regex matching on lowercased line
- Log level changed to INFO for rocminfo failures
- Multi-GPU support: iterates all GPUs, uses oldest for decision
Fixes#469
