strides missing methods for various AbstractArray subtypes

[musm]

Seems like some simple methods are missing for strides function

julia> strides(randn(5,5)')
ERROR: MethodError: no method matching strides(::LinearAlgebra.Adjoint{Float64,Array{Float64,2}})

similarily

julia> strides(transpose(randn(5,5))

and also other basic subtypes of AbstractArray such as Diagonal etc.

Is this still worked on? No method is available for BitArrays in Julia 1.4.1

julia> strides([1,0] .> 0)
ERROR: MethodError: no method matching strides(::BitArray{1})

Also NIVolume, the AbstractArray subtype from NIfTI.jl doesn't work with strides.
I defined a simple helper method for my project, as size is defined for all abstract arrays:

Base.strides(A::AbstractArray) = (1, cumprod(collect(size(A)))[1:end-1]...)

In Julia, we've used the stride terminology to talk about storage locations. BitArrays don't have strided storage locations, so they'll never support strides.

Thanks for your answer!
As I was looking for a different concept, I should name my function something like linear_neighbor_offsets.
And probably I should try to use the 'safe' way with LinearIndices.

This particular example is now fixed in #29135. I think we can roll the rest into the bigger #30432.
