QTextStream: use write(QChar) more

Replace write(&ch, 1) calls with write(ch) ones.

The QChar overload, added in 31c6d9f04ba80e6776ae01cb0588e6bd228f7184,
is safer, because it has less preconditions. With QTextStream being
security-critical, we should target to use safer functions to do the
same work, even if it introduces a bit of git history churn.

The call from a different TU (qdebug.cpp) means we need to remove the
lying inline keywords from both declaration and definition of
write(QChar), because GCC -Werrors on them.

As a drive-by, remove a use of QLatin1Char, in preparation of moving
from QChar to char16_t, eventually.

Pick-to: 6.10 6.9 6.8
