Description

The compact printing used within a Tuple etc. doesn't at present distinguish a CuArray from an ordinary Array:

julia> (; x = cu([1f0]))  # CUDA v3.4.2
(x = Float32[1.0],)

julia> (; x = [1f0])
(x = Float32[1.0],)

Maybe it should? This came up in https://github.com/FluxML/Zygote.jl/issues/1095 , but more generally Zygote likes to return tuples of arrays, and having a visible distinction might be helpful.

This could just be cu(Float32[1.0]) but perhaps that's not right for all eltypes.

Contributor guide

Research direction
Investigate how Julia's compact printing works for arrays and modify the show method for CuArray to include a 'cu' prefix in compact display, similar to how GPUArrays handle it.
