LinearAlgebra: 2-arg show for adjoint/transpose

[jishnub]

After this,

julia> t = [1,2]
2-element Vector{Int64}:
 1
 2

julia> show(transpose(t))
transpose([1, 2])

and similarly for Adjoint. This way, the displayed form is a valid constructor.

Edit: I've restricted this to cases where the parent is an AbstractVector, as this is the case where the difference between a dual vector and a matrix matters the most. A lazily transposed matrix is not all that different from the materialized form.

This is almost a dup of #40722

Indeed, I am happy to close this, but why was the other one stalled?

I don't know, most things stall! Would still be nice to have, I think.
