QPlatformMenu: add overloaded function 'showPopup' that takes a target rect

When showing an edit menu on touch platforms, you need to specify a target
rect for where to place the menu. The target rect is normally a rectangle
that encompasses the whole text selection. Using this information the OS
will place the menu so that is doesn't obscure the selection itself, or fall
outside the screen (or overlaps e.g the keyboard). Since we don't know the
size of the menu, or if the OS will end up placing the menu above or below the
pos we give it, we need to do it the correct way and forward the whole target
rect instead.
