[libc] Add check for locally installed GPUs
We need to know which, if any, GPUs the user has on their system if we
want to be able to test the `libc` source code for the GPU. This patch
adds a basic check using the `amdgpu-arch` utility which is provided by
`clang`.
Checking for NVIDIA GPUs will be done later as this is a little
problematic right now. CMake provides a method that we use for Clang but
it will soon be deprecated, the replacement requires a newer CMake
version that we will have in the LLVM 17 branch in the future. CUDA also
provides `__nvcc_device_query` but it's very new so I'm not sure if we
should rely on it. I may introduce a new tool to do it similar to
`amdgpu-arch`.
