LibPDF/CFF: Compute per-glyph glyph width in CID-keyed fonts

Browse source 
Make TopDict's defaultWidthX and nominalWidthX Optional<>s so that
we can check if they're set per fdselect-selected font dict, and
if so use the value from there in CID-keyed fonts. Otherwise, keep
using the value in the top dict.
