129a1a27 - [amdgpu-arch] Replace use of HSA with reading sysfs directly (#116651)

[amdgpu-arch] Replace use of HSA with reading sysfs directly (#116651) Summary: For Linux systems, we currently use the HSA library to determine the installed GPUs. However, this isn't really necessary and adds a dependency on the HSA runtime as well as a lot of overhead. Instead, this patch uses the `sysfs` interface exposed by `amdkfd` to do this directly.
