Khaled Hosny 3d12036000 Get rid of SalLayout::GetFallbackFontData()
This is only used in conjunction with SalLayout::GetNextGlyphs() in
vcl/source/gdi/pdfwriter_impl.cxx to retrieve the fallback font, if any,
used to layout the given glyph, but it is a very convoluted way to do a
straight forward thing, and hard to adapt for new SalLayout
implementations.

So now I just pass a fallback fonts array, when requested, in
GetNextGlyphs() itself.
