* fix(hipblas): symlink amdgpu.ids so ROCm backends find the ASIC ID table

ROCm's bundled libdrm_amdgpu looks up the GPU ASIC ID table at a
hardcoded fallback path, /opt/amdgpu/share/libdrm/amdgpu.ids, which is
only populated by AMD's full amdgpu-install (graphics/DKMS) stack. The
hipblas image is compute-only and doesn't have it, so every model load
logs "No such file or directory" and the GPU can't be identified.
Symlink it to the equivalent file already shipped by Ubuntu's
libdrm-amdgpu1 package.

Fixes #10624

* fix(hipblas): correct amdgpu.ids source package name in comment

Verified against the real rocm/dev-ubuntu-24.04:7.2.1 image with
hipblas-dev/hipblaslt-dev/rocblas-dev installed: /usr/share/libdrm/amdgpu.ids
is owned by libdrm-common, not libdrm-amdgpu1 as the comment said.
