[Bug libstdc++/31643] Codecvt facets with UTF-8 encoding fail to recognize partial encoding sequences

I ran additional tests just to make sure that the shift state was valid across
calls, even though partial is not returned when a chunk ends in a partial
encoding sequence.  I split several 2,3, and 4 byte UTF character sequences
across two calls to the codecvt in() method.  Each time, the sequence was
correctly widened into 1 UTF-32 character code.  Thus, the shift state appears
to be OK.  Just the return value of 'ok' is incorrect.
