tdf#149551 use 'WritingMode' instead of TextPreRotateAngle

Commit 7e23cbdbb6ec0247a29ed8a8f744c01e10963ea0 changed the code so,
that TextPreRotateAngle is used to track ooxml vert attribute. This
patch changes it so, that the style attribute WritingMode is used.
Now text direction can be written in 'writing-mode' attribute in the
graphic properties in ODF, same for shapes as for frames.

The needed conversion from WritingMode BT-LR and TB_LR90 to
TextPreRotateAngle for rendering of text in custom shapes is now in
one place in class SdrObjectCustomshape. The shape edit engine
cannot yet render it itself.

Some unit tests are adapted to use WritingMode property instead of
TextPreRotateAngle.

The value text::WritingMode2::TB_RL90 is introduced, corresponding to
vert='vert' and textDirection='tbRl' or ='rl' in OOXML. It is used
for frames too, so that the original text direction is preserved and
vert='eaVert' can be distinguished from vert='vert'.

TextPreRotateAngle is currently still used in SmartArt import for
'upr' and 'grav' and in emulating 'upright' but no longer to
emulate text direction.
