DirectWrite: Fix embedding fonts in PDF

If no filename is stored in the faceId() of the
font engine, then the PDF engine will bail out and embed
each glyph separately instead of embedding the font. This
would cause PDFs to be huge and unsearchable when high-dpi
was active, since we will automatically default to the
DirectWrite engine in this case.

[ChangeLog][QtGui][Windows] Fixed embedding fonts in PDF when
dpi scaling is active or when the hinting preference was
none or vertical hinting.
