Revert "QTextLayout: fix maximumWidth() for a text containing line separator"

This reverts commit 013c346a8dcbd618febb07884c64c740daf9754d. It was
determined to cause a regression in Qt Quick: QTBUG-106899.

In order to unblock integrations, we need to revert the change. It
can be re-committed later when the problem has been analyzed and
addressed.

Pick-to: 6.2 6.4
Fixes: QTBUG-106899
Task-number: QTBUG-89557
Task-number: QTBUG-104986
