QMainWindow: move the separator handling in another class

So it will be re-used by QDockWidgetGroupWindow

The Layout template argument can be the QMainWindowLayout,
or the QDockWidgetGroupLayout. They have a function
dockAreaLayoutInfo which return a QDockAreaLayout* or a
QDockAreaLayoutInfo*, respectively. These two class
have the same interface as far as QMainWindowLayoutSeparatorHelper
is concerned. (QDockAreaLayout forward most of its call to
the relevant QDockAreaLayoutInfo)

The code is mostly moved without modification, but there is a change in
startSeparatorMove, because we don't have access to the layoutState to
set the fallbackToSizeHints variable, so instead, we do that from
QMainWindowLayout::hover.
