    tdf#139301 fix OOXML-compatible preset dash styles

    Despite the purpose of the new interoperability styles
    added in commit b2d8093b19642038631dfb8f1ab6745a380a652c
    (tdf#127499 added 9 new line styles all are (var) and in line with MSO),
    collision with commit 57c9bdab377a00649299d1a4c9ed2f9e5e03b84e
    (tdf#127166, tdf#123903 improve import/export of line styles)
    resulted still missing interoperability on the user interface:

    1) opening an OOXML document, preset styles weren't recognized
       on the UI, also the preview was a solid line on the Drawing
       Object Properties toolbar.

    2) using the new compatibility preset styles, OOXML export
       resulted custom styles instead of the intended preset styles.

    On the UI, now the layout of the first 10 preset dash styles
    follows the OOXML standard, see 20.1.10.49 ST_PresetLineDashVal
    (Preset Line Dash Value) in ISO/IEC 29500-1, 2016:

        dash pattern    name (OOXML name)
    10                  "Dot"  (sysDot)
    1000                "Long Dot" (dot)
    1110                "Dash" (sysDash)
    1111000             "Long Dash" (dash)
    11111111000         "Double Dash" (lgDash)
    111010              "Dash Dot" (sysDashDot)
    11110001000         "Long Dash Dot (dashDot)
    111111110001000     "Double Dash Dot" (lgDashDot)
    11101010            "Dash Dot Dot" (sysDashDotDot)
    1111111100010001000 "Double Dash Dot Dot" (lgDashDotDot)

    Note: add missing "Dash Dot" (sysDashDot) and "Dash Dot Dot"
(sysDashDotDot).
    Remove "Double Dot": it really wasn't an OOXML-compatible preset
    style, and it has a good replacement among the older styles,
    the similarly loosely dotted "Fine dotted", which is still
    supported for back-compatibility.
