  [libc] Do not install to the default triple in GPU mode

Currently this logic causes the `libcgpu.a` to be installed to the
user's default triple. The GPU target isn't really true to this in a
cross-compiling sense so we should just default to the regular `/lib`
directory

  [libc] Add code for detecting NVIDIA GPUs as well

Recently the `nvptx-arch` tool was added to address the lack of a
similar tool for detecting locally installed NVIDIA GPUs. This patch
adds similar functionality for the already existing `amdgpu-arch` tool
in libc. These will be used to run tests on the user's system in the
future. On a system with both GPUs installed we will just go with the
first GPU detected. In the future we may want to configure the tests to
run on both of them.
