Introduce multiple language based font fallback.
The motivation of this CL is enhance the font fallback score design to support multiple language font fallback. This CL contains following changes: - Break language based font score into two: script-based score and primary-language-based score. - The primary-language-based score is 0 if the script-based score is 0. If the script-based score is not 0 and the primary language is the as same as the requested one, the font gets an extra score of 1. - The language score gets a higher multiplier for languages higher in the locale list.
