Use SparseMatrixColorings

[gdalle]

DI source

• Remove all the coloring and decompression logic to replace it with the functions from SparseMatrixColorings.jl v0.3
• Store more things in the sparse Jacobian and Hessian extras to replace the Compressed type
• Add a fully out-of-place Jacobian and Hessian
• Make sure that all the functionality used belongs to the public API of SMC (right now color_groups is still private)

DI docs

• Document the fact that GreedyColoringAlgorithm comes from SparseMatrixColorings.jl and is just reexported, add necessary interlinks

DI tests

• Add more tests on sparse backends with sparse scenarios (ForwardDiff, Zygote, Enzyme, ForwardDiff/Zygote)
• Keep tests on sparse backends with dense scenarios
• Remove MyAutoSparse and instead be explicit every time
• Re-add type stability tests for ForwardDiff

DIT source

• Make type stability tests do nothing on < 1.7 where JET isn't usable

DIT CI

• Split CI in groups like for DI
