axistype should create OneTo for better similar support

[chriselrod]

When broadcasting with array types that returned static(1):N for axes, we'd get OffsetArrays instead of Arrays. These should hopefully now generally be returning Arrays instead:

  @test identity.(static(1):5) isa Vector{Int}
  @test (static(1):5) .+ (1:3)' isa Matrix{Int}
  @test similar(Array{Int}, (static(1):(4), Base.OneTo(4))) isa Matrix{Int}
  @test similar(Array{Int}, (static(1):(4),)) isa Vector{Int}

Under this PR, if the first OptionatllyStaticUnitRange{StaticInt{1}} occurs in index 3 or later of the tuple, it'll still result in an OffsetArray, but I figured getting these cases is enough.
It'd just require copy/pasting and adding more methods if we wanted to support deeper indices with the current approach.
