More prominently document JULIA_CUDA_USE_BINARYBUILDER

Runtime downloading of artifacts at module __init__ is a real pain for deployment, especially for parallel workloads. Would it be possible to move the lazy downloading of the artifact to Pkg.build()?

It would also be useful to have a mechanism to save these preferences so that they persist between sessions/versions (FFTW.jl and MPI.jl save their preferences to a file in .julia/prefs/, but JuliaLang/Pkg.jl#1835 will hopefully provide a more systematic way to do this).

Why not call CUDA.version() or something when you install the package? I'd rather not add even more functionality that should really live in Pkg here to support (pretty niche) use cases, the current set-up is complex enough already.

This is now mentioned on the main installation overview docs: https://juliagpu.gitlab.io/CUDA.jl/installation/overview/
