tdf#112450 correct points and size for polyline in VML import

The points in file source might have units. Decode was missing.

maWidth and maHeight are used in ShapeBase::convertAndInsert(), and
moCoordSize is used in PolyLineShape::implConvertAndInsert(). So
ShapeContext needs to provide both in case of importing a polyline.
That was missing.

Word writes the size into the coordsize attribute of the v:polyline
element. But from VML specification it need not exist, but bounding
rectangle of points has to be used. That is added too.

Unclosed polyline cannot be filled in LO and ODF, a fill is only
possible for a closed polygon. LO defines a sequence of points as
being closed, if first point == last point. The import is adapted
to that behavior.

Word allows an unclosed polyline to have filling. That cannot be
represented with a simple PolyPolygonShape but would need a
CustomShape. Because the user cannot yet edit points in a CustomShape
but can do that in a PolyPolygonShape, the v:polyline element is
not converted to a CustomShape on import and not to DML on export.
LO would first need an UI for editing points of a CustomShape.
