ohos: simplify pickColor by using QThreadSafeRef

Now that the color-picking implementation lives inside QOhosColorPicker,
which is a QObject, use the plugin's standard QThreadSafeRef idiom for
the result callback instead of a hand-rolled QObject context plus a
shared_ptr/weak_ptr guard. This drops the local Context struct, the
manual QMetaObject::invokeMethod() dispatch and the
m_ohosColorPickingHandle member, and the picked QColor is now emitted
directly without the QOhosOptional<quint32> round-trip.

Behavioural note: the old m_ohosColorPickingHandle member made a second
pickColor() call suppress the colorPicked() emission of an earlier
still-pending pick; overlapping picks now both emit. This is harmless in
practice, as the picker is a modal screen UI that cannot start a second
pick while one is in progress.
