parts: use ceilf(ch->advance) for text layout

Fixes an issue in English version of Rance 9 where item description text
was overly compressed. Now ChipmunkSpriteEngine.SP_GetFontWidth returns
the same values as the official engine.

There are still text layout bugs with item descriptions in Rance 9
(affecting both JP and EN versions), but this at least makes the text
readable.
