Rebase of #33363.

This allows to concatenate matrices, numbers and uniform scalings.

Fixes JuliaLang/LinearAlgebra.jl#666. Closes #33363.

Interestingly (for the type system), this made the humble call methods(hvcat, (Tuple{Int,Int},Any,Any,Any,Any,Any,Any,Int,Int)) take >50 seconds, which also affects some compile times.

@JeffBezanson So how do we handle this slowdown? #41511 is a small PR on top of this one to avoid method ambiguities. Are we going to keep this one here and try to improve it or revert it and tackle the issue from scratch with latency checks included?

Scratch that, I just saw that #41511 already has a triage label.
