Qt Designer: Write out forms with unqualified enums for older Qt versions
This partially reverts 67c7d6e which was not covering the Line orientation and implements it for all properties. Modify the code introduced by a52c1be to depend on the Qt version. Move the SerializationMode enumeration to the base class MetaEnum and add a mode for compatibility forms. Remove the unused NameOnly flag. Pick-to: 6.7 6.7.3 Task-number: PYSIDE-2492 Task-number: QTBUG-118473 Task-number: QTBUG-127179 Task-number: QTBUG-128365 Change-Id: I4e7efc1545bf35cac5e54c7d385fc1eaf0b484ef Reviewed-by: Jarek Kobus <[email protected]> (cherry picked from commit 1a655fd)
