dev-libs/cutlass: add 4.1.0
add code for -9999 version
allow USE=headers-only with USE=tools
add missing gtest dep
cleanup USE=clang-cuda
- including setting correct CUDA_HOST_COMPILER ( this will break with to new
clang, but that isn't supported well enough yet )
pass all-major when CUDAARCHS is unset
lower test level to 0
run tests in serial to avoid broken inter test dependencies
