This lays the groundwork for making SparseBitSet serializable. FontFamily.addFont is only used when the FontFamily is constructed. Thus, instead of calling FontFamily.addFont multiple time, passes Font list to the constructor. By this change, FontFamily can be immutable now. By making FontFamily immutable, We can create FontFamily with pre-calculated SparseBitSet. Bug: 34042446 Test: minikin_tests has passed Change-Id: I2576789fba6cb27687e920e2488e8bedbcf7d36f
