As we already rely on the GlyphItem's font instance, consequently this removes the SalGraphics GlyphItem based functions. Also unifies the glyph bound rect cache handling. An interesting aspect is the rotated glyph bounding box handling moved from CairoTextRender to FreetypeFont. It doesn't look like an implementation detail for Cairo, so it may have been a bug.
