gdiplus: Use font emSize to map to pixel size instead of using gdi32 font metrics.

[Dmitry Timoshkov]

GdipCreateFontFromLogfont has no choice but use what gdi32 provides (and the
tests show that it does that correctly), GdipCreateFont has an application
provided emSize and does correct mapping from emSize to lfHeight, so let's do
the same in GdipGetLogFont.

This patch fixes the regression reported in the bug 30724.
