Rewrite UTF-8 encoding.

Create a templated implementation to serve all the UTF-8
related encodings. Use it for `CharsetUtils.toUtf8Bytes()`
and the JNI `GetStringUTFChars()`. Do not use it yet for
the internal `ConvertUtf16ToModifiedUtf8()` which shall be
switched to actual Modified UTF-8 in a separate change.
