[libclc] Update default triple support for AMD and deprecate 32-bit PTX (#174415)

Browse Source 
Summary:
The standard `nvptx` target is not supported and has been completely
removed following the CUDA 12 release. It should be safe to drop support
for it in the default build. Additionally we add the `amd` vendor to the
amdgcn triple as this is the more canonical form and builds the same IR.
