Cartesian indexing for SubArrays with non-integer AbstractRanges

[jishnub]

With #50457 now merged, an AbstractRange of CartesianIndexes should use CartesianIndexing in constructing a SubArray. I've limited the method to integer ranges, as this is the case where we know for sure that the indexing may be linear.

Fixes

julia> view(1:2, StepRangeLen(CartesianIndex(1), CartesianIndex(1), 0))
0-element view(::UnitRange{Int64}, StepRangeLen(CartesianIndex(1,), CartesianIndex(1,), 0)) with eltype Int64

Good to go?
