scaled-font: Optimize cairo_scaled_font_lookup()
By tracking which fields of information are already available on the
scaled_glyph we can more efficiently determine if we already have the
requested fields. This reduces from about 6 conditionals to one, and
reduces the function overhead by ~20% -- which has a measurable
improvement on glyph benchmarks.
