[psaux] Fix CFF advance widths. (#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer. Remove unused fields. * src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy to reference. Remove unused. * src/psaux/psft.c (cf2_setGlyphWidth): Update code.
