emfplus: migrate gdiplus reader to drawinglayer

In the current state interpretation of the GDI+
data is needed in the MetafilePrimitive in the
drawinglayer project. Migrate helper stuff and
reader from cppcanvas to drawinglayer as tooling,
prepare tooling, prepare changing from direct
canvas rendering, isolate and migrate existing
tooling from MetafilePrimitive from reading emf/wmf
to places where it can be commonly used by both,
prepare cange of different graphic statue usages,
start changing XForm to B2DHomMatrix conversions,
