BIM/Help: Access DockWidgetArea QFlag enum correctly

Currently, for both Help and BIM Views panels we can get a traceback
about incorrect casting if we move the panel.

This is because the QFlag of DockWidgetArea that is being passed, as it is not
able to be parsed down to an int. Most probably some historical change
either in Qt or FC.

This error also caused to not write current BIM Views/Help panel setup
to config, resulting in the position being resetted every run.
