xcb: Replace qCWarning by qCDebug in QXcbConnection::printXcbError()

Example:
Error "BadWindow" (3) is raised by the XCB backend when a mouse event
is processed on a resource that disappears between posting and
processing of the event.
That constellation is harmless and can occur in async environments.

As XCB errors point to coding issues, this patch changes their logging
behavior from qCWarning to qCDebug.

Fixes: QTBUG-56893
Pick-to: 6.4 6.3 5.15
