66e94107 - Add a fully typed Diagonal constructor from `AbstractMatrix`es (#52487)

Add a fully typed Diagonal constructor from `AbstractMatrix`es (#52487) The following works after this PR: ```julia julia> oftype(Diagonal(Float32[1,2]), [1 0; 0 2]) 2×2 Diagonal{Float32, Vector{Float32}}: 1.0 ⋅ ⋅ 2.0 ``` This changes the behavior of the constructor to copy the diagonal, so now ```julia julia> D = Diagonal([1,2]); julia> typeof(D)(D).diag === D.diag false ``` whereas this used to be `true` previously. This probably doesn't matter much, as in most non-trivial cases it'd be copied anyway, and this conversion is unusual in the trivial case. --------- Co-authored-by: Daniel Karrasch <daniel.karrasch@posteo.de>
