Switch to ADTypes.jl v1.0

[gdalle]

• Define TracerSparsityDetector following the AbstractSparsityDetector framework of ADTypes v1.0
• Remove SparseDiffTools extension
• Add tests
• Add docs
• Commit manifests and tweak docs CI because ADTypes v1.0 is not released
• Put test extras in the main project file to avoid "cannot merge projects" error JuliaLang/Pkg.jl#1585

Do you need this now?
I'd like to wait a little bit longer and add proper Jacobian and Hessian tracer types.
And ADTypes v1.0 isn't registered yet.
