Anticipate new AMReX options in CMake.
Also introduces a new environment hint,
AMReX_CUDA_ARCH, that we can use inwarpx.profilefiles to default-optimize for CUDA architectures. Currently, as well as without the hint, CMake will try to find out local GPUs by running a small executable that queries the device capabilities. If the login node has no GPUs or the run does not succeed we fall back to potentially unoptimized default architectures (6.0+).Ref.: AMReX-Codes/amrex#1490
