Use Utils::SkipEmptyParts instead of the deprecated one in QString

- Qt 5.14 introduced Qt::Keep/SkipEmptyParts and deprecated these in
QString namespace.
- Qt Creator defined Utils::SkipEmptyParts conditional on the Qt version,
so we use that for flexibility.
- Remove any explicit references to QString::KeepEmptyParts, as it's a
default value.
