Raising the baseline for the `nvptx64-nvidia-cuda` target

Rust 1.97 is raising the baseline requirements for NVIDIA GPU compilation targets.

• •PTX ISA version increases to 7.0, requiring CUDA 11 or newer driver
• •GPU architecture minimum raised to SM 7.0, dropping support for GPUs older than 2017
• •Changes address compiler defects that caused crashes and miscompilations
• •Users targeting older CUDA drivers or GPUs must update their -C target-cpu flag
• •New default will be sm_70 when no target-cpu is specified
