Remove the unused raw field from the CFFCharset class

[Snuffleupagus]

This was necessary before charset compilation was implemented, however that's been supported for many years and this is just dead code now.

• PR Map all glyphs to the private use area and duplicate the first glyph. #9340, back in 2018, stopped using the raw field.
• PR Add unique glyph names for CFF fonts. #10591, back in 2019, implemented proper charset compilation.
