Include-what-you-use related to logging.h (gin)

Add direct includes for things provided transitively by logging.h
(or by other headers including logging.h).

This is in preparation for cleaning up unnecessary includes of
logging.h in header files (so if something depends on logging.h,
it needs include it explicitly), and for when logging.h no longer
includes check.h, check_op.h, and notreached.h.
