  [cff] 32bit integer overflow run-time errors 2/2 (#46149).
  
  This commit handles the new engine.
  
  * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT32,
  OVERFLOW_SUB_INT32, OVERFLOW_MUL_INT32, NEG_INT, NEG_LONG,
  NEG_INT32): New macros.
  
  * src/cff/cf2ft.c (cf2_getScaleAndHintFlag): Use OVERFLOW_ADD_INT32.
  
  * src/cff/cf2hints.c (cf2_getWindingMomentum, cf2_hint_init,
  cf2_hintmap_map, cf2_glyphpath_hintPoint,
  cf2_glyphpath_computeIntersection, cf2_glyphpath_computeOffset,
  cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): Use
  OVERFLOW_ADD_INT32, OVERFLOW_SUB_INT32, OVERFLOW_MUL_INT32, and
  NEG_INT32 where appropriate.
  
  * src/cff/cf2intrp.c (cf2_doFlex, cf2_doBlend,
  cf2_interpT2CharString): Ditto.
  Also add some other code where needed to avoid overflow.
