LibTextCodec+AK: Don't validate UTF-8 strings twice
UTF8Decoder was already converting invalid data into replacement characters while converting, so we know for sure we have valid UTF-8 by the time conversion is finished. This patch adds a new StringBuilder::to_string_without_validation() and uses it to make UTF8Decoder avoid half the work it was doing.
