  [NVPTX] Enable i128 support in the NVPTX backend (#98658)

Summary:
The target information needs to configure that the platform has a
maximum integer size of 64 in order for it to enable i128 support. The
motivation behind this patch is that the i128 libcalls seem to be the
only ones used by the NVPTX backend and it would be ideal to disable
those completely. That would allow LTO to optimize libcalls properly
after https://github.com/llvm/llvm-project/pull/98512.
