Introducing the PlatformPanel event type.

This event can be used by any platform plugin to implement
special application panels/overlayed menus.

Currently used by QNX only.

This replaces sending fake Qt::Key_Menu presses in the QNX
plugin. Qt::Key_Menu is already used when invoking context
menus with the keyboard.

( backport of qtbase/9695df4d44b228e7e778ff17d5cccac30967b1fd )
