[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.
