[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.
