CUDA: Add support for CUDA_ARCHITECTURES=native

CUDA 11.6 added the `nvcc -arch=native` flag to automatically compile
for the host GPUs' architectures.  Add support for specifying this
special `native` value in `CMAKE_CUDA_ARCHITECTURES` and
`CUDA_ARCHITECTURES`.  During the compiler ABI detection step,
detect the native architectures so we can pass them explicitly
when using Clang or older versions of nvcc.

Fixes: #22375
