Window: Focus custom titlebar with F10

As discussed on desktop-devel-list [1], "There should be an intuitive,
consistent, immediate way to jump to the widgets that live in the
header bar." F10 has been suggested for this as it is already used to
active menubars.

F10 will focus the custom titlebar widget if the window has one and it
isn't already focused. If the titlebar widget doesn't exist or is
already focused then F10 focuses the menubar if there is one.

wayland: Fix submenu positioning

window->x / window->y are in "root window coordinates", e.g. relative
to the topmost toplevel. However, the coordinates in get_xdg_popup are
relative to the passed-in surface, so we need to do the reverse
translation here.

a11y: Make GtkWindowAccessible know about popovers

a11y: Add private GtkContainerAccessible functions to add/remove a child

This may be useful in container implementations, or for internal children
that trigger no signal emission.

https://bugzilla.gnome.org/show_bug.cgi?id=725864
window: Emit a11y signals directly on popover added/removed

As those are internal children, there's no signal that GtkWindowAccessible
could catch when those are added or removed, so make GtkWindow use the private
GtkContainerAccessible methods to add/remove the child accessible when that
happens.

a11y: Add GtkPopopverAccessible

And let GtkPopover use it as its GtkAccessible implementation, this
accessible sets the POPUP_FOR relationship to the relative-to widget,
and keeps track of changes there.

a11y: Don't allocate a list just for counting widgets in GtkContainerAccessible

It's more straightforward if counting through gtk_container_foreach().
entry: postpone magnifier creation until when needed
entry: postpone text handles creation until when needed

This is only necessary for touch devices, so unlikely in many setups.
entry: revert text handles to cursor mode after cut/paste

The current text selection goes away in that case, so reflect
that too in the handles.
textview: Postpone magnifier creation until when needed

This is only necessary for touch devices, so unlikely on many setups.
