window: Add raise_and_make_recent() method

Browse Source 
After !2489, the active workspace's MRU list is now used to pick
the next focus window instead of the stack order.

This list is currently only updated on focus, which can lead to
surprising behavior when closing a window after activating its
ShellApp in the shell.

That is because raising a window (as part of shell_app_activate())
will only change the stacking order, so when closing the active
app window, the focus will switch to whatever had focus before the
app was activated, not the app's next window.

In order to allow gnome-shell to address this, add a new
raise_and_make_recent() method that also adjust the MRU order.
