How did you determine all of these requirements? Are these strict requirements or guesses?

I don't understand the package manager too well, but I have run into some tricky issues with dependency-validity occasionally; will be good if this PR helps avoid that (and does not introduce new issues).

The CUDA packages and GPUifyLoops are strict requirements because we rely on recent features.

For the other packages I just used the version we currently have specified in Manifest.toml as we haven't had problems with the current environment (and tests pass). I assumed that future versions will be compatible to avoid having to constantly update upper bounds, but if a new version of a package introduces problems we can add upper bounds. I added ^1 for packages that may release a v1.0.
