cannot assign to ustriped AbstractArrays

it sure would be nice if Unitful played better with CuArrays. for example, currently, one cannot `ustrip` a `CuArray` and then assign to it:

```
julia> using Unitful, CUDA

julia> c = CuArray(zeros(3) * 1u"s")
3-element CuArray{Quantity{Float64, 𝐓, Unitful.FreeUnits{(s,), 𝐓, nothing}}, 1, CUDA.Mem.DeviceBuffer}:
0.0 s
0.0 s
0.0 s

julia> ustrip(c)[1]=1 # innocuous warning about scalar indexing removed for succinctness
1

julia> c
3-element CuArray{Quantity{Float64, 𝐓, Unitful.FreeUnits{(s,), 𝐓, nothing}}, 1, CUDA.Mem.DeviceBuffer}:
0.0 s
0.0 s
0.0 s
```

however, if i simply add a new method identical to [this one](https://github.com/PainterQubits/Unitful.jl/blob/9e329e8e7200b3e42e0a6676d2948c66d35061b4/src/utils.jl#L78) but with `CuArray`, then it works fine:

```
julia> import Unitful: ustrip

julia> @inline ustrip(A::CuArray{Q}) where {Q <: Quantity} = reinterpret(Unitful.numtype(Q), A)
ustrip (generic function with 16 methods)

julia> ustrip(c)[1]=1
1

julia> c
3-element CuArray{Quantity{Float64, 𝐓, Unitful.FreeUnits{(s,), 𝐓, nothing}}, 1, CUDA.Mem.DeviceBuffer}:
1.0 s
0.0 s
0.0 s
```

to be all inclusive, i think the right way to go here is just use `AbstractArray`. then it'll work too for MtlArray, ROCArray, etc.

Start with src/utils.jl at the linked ustrip method and inspect how its array dispatch is defined. Confirm the behavior with the CuArray example; done when ustrip permits assignment through the returned array while preserving the original quantity array, including other AbstractArray implementations mentioned in the issue.
