Add lazy = true to Artifacts.toml

[odow]

@noahrhodes can you try: ] add Gurobi_jll#odow-patch-1

x-ref jump-dev/Gurobi.jl#564

Hmm. Have some local failures, so tests might be passing because of the cache. Taking a look.

So the issue is that our __init__ functions require the artifact:

I wonder if we can futz with ccall(:jl_generating_output, Cint, ()) == 1 so that we delete the license only if the library is actually loaded by the user. I don't think so

Closing because there's no point in this until we have LazyJLLWrappers.
