GSoC: Enable building Harfbuzz with Graphite
Harfbuzz will now need to be built with Graphite support. This allows
Harfbuzz to handle Graphite fonts. In case we all building with
system Harfbuzz, then it should be built with Graphite support else
we error out.

GSoC: Remove DrawServerFontLayout and add DrawSalLayout
DrawServerFontLayout is removed. A more generic function DrawSalLayout
with two different signatures is added. This allows the appropriate
function to be used depending on the platform.

GSoC: Move code from winlayout.cxx to winlayout.hxx
WinFontInstance definition moved to winlayout.hxx. It has to be used
in the new layout class. Code and headers which WinFontInstance
depends on also moved to winlayout.hxx
