For legacy reasons, we kept around the use of UTF-16 internally in AAPT2. We don't need this and this CL removes all instances of std::u16string and StringPiece16. The only places still needed are when interacting with the ResTable APIs that only operate in UTF16. Change-Id: I492475b84bb9014fa13bf992cff447ee7a5fe588
