Some window managers use fading effects to close popups, resulting on
an unnatural animation if menus close from parent to child.

Some limitations in MouseArea force us to abandon the "one mouse area
per menu item" implementation in favor of a menu-wide mouse area,
where we track the position changes to highlight the menu item under
the mouse cursor. This makes possible updating the highlighted menu
item while keeping the mouse pressed.

Also, we need to emit an extra mouse press event, from the menu popup
window, so that the menu mouse area will receive any mouse release
event the user may have triggered. This is because the initial mouse
press event popping up the menu was made in another window, and
MouseArea would only emit 'released' signals if the released button
was already pressed.

When popping up a menu with the mouse cursor under a certain item, the
visual item coordinates may be resolved too late. To solve this, we
listen to the item's position and update the popup window's position
accordingly, in a similar fashion as we did for its size.

This removes one dependency from QtWidgets.

QPA is only implemented for Mac so far, and depends on qt/qtbase's
I5f83f260602f55b9409ad69abf670afb59b2d33a change. This means, it will
only work with Qt 5.1 and older. Other QPA implementations will
follow, like Android.

The QML-only implementation has been tested mostly on Linux. On Mac,
we need I4716b4c0b6187d14adb34c46b848ca0a16370b5a to be integrated in
qt/qtbase dev branch if we want to enforce non-QPA menus.

Updated ComboBox, ContextMenu to new QPA menu behavior

Includes preliminary documentation for Action, ExclusiveGroup,
MenuBar, MenuItem, MenuSeparator, and Menu.
