Move QShortcutMap to QtGui

QShortcut stays in QtWidgets, what we need in QtGui
is only the basic functionality of the shortcut map.
QML can integrate directly with the map where required.

+    \class QShortcut
+    \brief The QShortcut class is used to create keyboard shortcuts.
+
+    \ingroup events
+    \inmodule QtWidgets
+
+    The QShortcut class provides a way of connecting keyboard
+    shortcuts to Qt's \l{signals and slots} mechanism, so that
+    objects can be informed when a shortcut is executed. The shortcut
+    can be set up to contain all the key presses necessary to
+    describe a keyboard shortcut, including the states of modifier
+    keys such as \gui Shift, \gui Ctrl, and \gui Alt.
+
+    \target mnemonic
+
+    On certain widgets, using '&' in front of a character will
+    automatically create a mnemonic (a shortcut) for that character,
+    e.g. "E&xit" will create the shortcut \gui Alt+X (use '&&' to
+    display an actual ampersand). The widget might consume and perform
+    an action on a given shortcut. On X11 the ampersand will not be
+    shown and the character will be underlined. On Windows, shortcuts
+    are normally not displayed until the user presses the \gui Alt
+    key, but this is a setting the user can change. On Mac, shortcuts
+    are disabled by default. Call qt_set_sequence_auto_mnemonic() to
+    enable them. However, because mnemonic shortcuts do not fit in
+    with Aqua's guidelines, Qt will not show the shortcut character
+    underlined.
+
+    For applications that use menus, it may be more convenient to
+    use the convenience functions provided in the QMenu class to
+    assign keyboard shortcuts to menu items as they are created.
+    Alternatively, shortcuts may be associated with other types of
+    actions in the QAction class.
+
+    The simplest way to create a shortcut for a particular widget is
+    to construct the shortcut with a key sequence. For example:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qshortcut.cpp 0
+
+    When the user types the \l{QKeySequence}{key sequence}
+    for a given shortcut, the shortcut's activated() signal is
+    emitted. (In the case of ambiguity, the activatedAmbiguously()
+    signal is emitted.) A shortcut is "listened for" by Qt's event
+    loop when the shortcut's parent widget is receiving events.
+
+    A shortcut's key sequence can be set with setKey() and retrieved
+    with key(). A shortcut can be enabled or disabled with
+    setEnabled(), and can have "What's This?" help text set with
+    setWhatsThis().
