    ctf: fix incorrect CTF for multi-dimensional array types

    PR debug/114186

    DWARF DIEs of type DW_TAG_subrange_type are linked together to represent
    the information about the subsequent dimensions.  The CTF processing was
    so far working through them in the opposite (incorrect) order.

    While fixing the issue, refactor the code a bit for readability.
