[autofit] Add support for Mongolian script.

As a de-facto standard, layouts using this script are constructed horizontally line by line, then the lines are rotated clockwise for vertical display. * src/autofit/afblue.dat: Add blue zone data for Mongolian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Mongolian standard characters. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Mongolian data.
