DirectWrite: Fix calculating bounding box of glyphs

We don't support vertical text layouts in Qt, so the vertical
advance should always be 0 (like it is in other engines).
Since we were setting this, we would calculate the bounding
box of strings in the DirectWrite engine as if the layouts
were diagonal, adding up both the horizontal and vertical advances.

[ChangeLog][QtGui][Windows] Fixed height of text bounding box when
using no or vertical hinting preference, or when the device pixel
ratio is different from 1.
