Fix printing multiple copies in wxMSW.

If wxPrinterDC was created by the native "Print" dialog for a printer that
supports printing multiple copies, we must not manually print multiple copies
ourselves as this results in too many copies being printed. However we still
need to loop explicitly for wxPrinterDC objects created manually or for the
printers without support for multiple copies (supposing they still exist).

Closes #10323.

Ensure that detached menus don't keep focus grab in wxGTK.

A widget being hidden must remove its focus grab with GTK+, otherwise GTK+
would continue sending all input messages to it but fail to process them
because the widget is not realized any more, resulting in a complete freeze of
the entire program.

Do it when detaching menus from menubar and menubar from the frame to fix just
such a problem in case SetMenuBar() was called while the previous menubar was
opened.

Closes #15221.

Reset row and columns count in wxRichTextTable::ClearTable().

No real changes, just update the internal variables in ClearTable() to avoid
inconsistent internal state, even if this doesn't seem to result in any
problems for now.

Closes #15190.
