  [libc] Use `nvptx_kernel` attribute in NVPTX startup code

Summary:
A recent patch allowed us to emit a callable kernel from freestanding
NVPTX code. This allows us to move away from using the CUDA language.
This has several advantages in that it works around an entire assortment
of errors I was seeing while implementing RPC for Nvidia.
