libstdc++: Remove leftover __formatter_chrono base classes.
This patch removes the __formatter_chrono<_CharT> base class from the
formatters for utc_time, gps_time, and tai_time. These formatters
are using the __formatter_duration<_CharT> member only.
libstdc++-v3/ChangeLog:
* include/bits/chrono_io.h (formatter<chrono::utc_time, _CharT>):
(formatter<chrono::gps_time<_Duration>, _CharT>)
(formatter<chrono::tai_time<_Duration>, _CharT): Remove
__formatter_chrono base class.
