string_decoder: rewrite implementation
This commit provides a rewrite of StringDecoder that both improves
performance (for non-single-byte encodings) and understandability.
Additionally, StringDecoder instantiation performance has increased
considerably due to inlinability and more efficient encoding name
checking.
