Change language score calculation in the calculation of the font family. Instead of language and script matching, a match in subtag is added. In addition, a match in subtag has a higher priority than a match in script. The score levels are divided into 5 score levels and the limit of the number of font languages is changed to 12 from 17. Multiple languages selection rule could to be added in the future. Bug: 31608997 Test: Done by unittests. Change-Id: I1e7177095f604fd1794bc99ca36c705dcb4c56e7
