03d2376745 [math] Improve fuzzing coverage 
Extend testing to cover parts that are missing according to the recent
oss-fuzz-coverage report:
- Retriving all constants from MathConstants.
- Retrieving entries from MathKern, MathGlyphPartRecord and
  MathGlyphAssembly.
- Retrieving italic correction from MathGlyphAssembly.
- Choosing between horizontal/vertical offset in MathVariants.

dfc5e5a27d [test] Skip glyph positions for test failing on CI 
We are not interested in glyph positioning for this test, and the
FreeType version on some CI machines is giving some different glyph
advances here.

c3f590bb1e [arabic] Support legacy PUA shaping 
Support legacy pre-OpenType Windows 3.1-era fonts, by remapping PUA code
points in cmap table and letting our fallback shaper build the GSUB
table.

Uniscribe applies also mset-like substitution, but our fallback mark
positioning gives better results, so this is not implemented.

af74ab452f [repack] always run the sort in repack. 
This is needed to ensure virtual link ordering constraints are respected when repack is being called from fontTools. For subset usage, repack won't be called if the graph doesn't already overflow so this change doesn't cause any extra work.

them from git history.
