tdf#80822 Convert MM progress dialogs to modal

The mail merge wizard is already modal to the source window. As
long as the mail merge isn't finished, there is is no useable way
to interact with the wizard. So make the progress window modal to
the mail merge wizard to prevent the crashes when the user cancels
the wizard while a mail merge is run.

As the progress dialog can be triggered via UNO, the dialog has
still has to be created as a non-modal floating window, when not
called from the mail merge wizard.
