logging.h related include-what-you-use (fuchsia/)

Fix code that was implicitly depending on logging.h or its
dependencies.

For example, code that uses DISALLOW_COPY_AND_ASSIGN should
include base/macros.h, but it currently happens to work if
it pulls in logging.h directly or through some dependency.

This is part of refactoring the codebase to use
check.h/check_op.h for the CHECK and CHECK_op macro
instead of logging.h.
