This commit removes all the uses of Shell.GenericContainer from
SwitcherPopup.SwitcherList. Compared to the other patches, this
one was specially trickier to get right, and a few invasive
changes needed to be done.
The most noticeable one is that the allocation of the items is
done entirely by St.BoxLayout -- we don't manually allocate them
anymore. To make it work, get_preferred_width() had to calculate
the correct value. It now assumes that:
* Minimum width: the minimum width of the widest child.
* Natural width: the minimum width of the StBoxLayout (use it
instead of the natural width to force the labels to ellipsize
when too long.)
The AppIcon class became a St.Widget subclass as well, to override
get_preferred_width() and be able to keep the squared shape.
Besides that, add a new SwitcherButton class to reimplement squared
icons without having to resort to hacks in the size allocation
machinery. This class has a single vfunc override to ensure that it
is squared when the SwitcherList is.
The arrows indicating multiple windows are now in this._list
actor to the SwitcherPopup itself, since this._list automatically
manages its own children now.
At last, adapt (but preserve) the hack in CyclerPopup.

Instead of overriding vfunc_get_preferred_width|height(), use the
already available Layout.MonitorConstraint to bind SwitcherPopup
to the primary monitor.
This commit turns SwitcherPopup.SwitcherPopup into a St.Widget
subclass, and gets rid of Shell.GenericContainer usage. Subclasses
were adapted to that too.
This class introduced a new challenge: it overrides show(). As per
discussions, we now call this.visible = true inside show().

In the process of purging all usages of Shell.GenericContainer
of GNOME Shell, one specific problematic situation that might
occur is when classes have functions that would clash with any
ClutterActor or StWidget function name.
One of such example is SwitcherPopup.destroy(). Right now, this
class is a pure JavaScript class that wraps a real actor, but
soon this will change, and it'll become a St.Widget subclass.
Another problem with functions that mimic the toolkit ones is
the predictability of them; after calling destroy(), that widget
is expected to not be available anymore. In SwitcherPopup case,
it is still available for a short while. In this case, that's not
a big problem, but the show() and hide() functions in other clases
are more problematic because the actor's visibility does not
follow that.
This commit is a first step in cleaning that up, and changes the
SwitcherPopup.destroy() to fadeAndDestroy().

If the Escape key is used for a window/app cycler/switcher shortcut
(such as "Switch windows directly"), then there is no way to cancel
the switching/cycling operation with the keyboard.
This change allows cancelling such an operation by pressing the Tab
key, but only if Tab is not already being used by the current
switcher/cycler shortcut.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

This will be mainly useful for closing apps from the applications
switcher, but can be implemented generically enough to select the
nearest existing item after removal if there's any, or destroying
the popup's actor otherwise.
Specifically for the apps switcher, doing this also removes the need
of having to manually either update the current app in AppSwitcher
and highlight it, if there are still any items after the removal, or
simply destroy the AppSwitcher otherwise. Besides, calling _select()
in the handler for item-removed makes sure that the list of thumbnails
in the switcher is always closed, if open, when quitting the app.

Make sure that the items from the applications switcher and the windows
switcher are removed when the related applications get stopped, or some
of the associated windows closed.

This drops the requirement that SwitcherPopups need a modifier based
keybinding to work.
The existing behavior for modifier based keybindings is kept but if
the popup is triggered from a no modifiers keybinding, instead of
finishing when the modifier is released, we use a timer that
automatically finishes the popup. The timer is reset on every key
release to allow navigation to happen.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

If the popup happens to be mapped beneath the pointer, mutter will now
emit an implicit enter notify event (i.e. not caused by pointer motion).
In this case the switcherPopup still goes and selects the item, which
results in too sensitive alt-tab menus if the pointer happens to be in
the wrong place.
Make highlighting rely on motion events instead, so it always involves
user interaction when triggered by the pointer.

We don't really need this step as a separate method since all
implementations are supposed to be created and shown immediately. This
also ensures that we have items to show in all subclasses.

All derived classes are already checking explicitly for action names
(FOO and FOO_BACKWARDS). mutter used to have a META_KEY_BINDING_REVERSES
flag for keybindings which required special handling of "shift"+FOO as
FOO_BACKWARDS, but this has been removed now, so this special handling
is no longer necessary.

We had one osdWindow that we displayed either on the primary monitor or on
whatever monitor index got passed over dbus.
Change that to show the osd on all monitors when no explicit monitor is
requested. A monitor should be requested in cases like display brightness where it makes sense to only show the osd on the affected monitor.

Without special-casing, our current spacing calculation results in
negative size requests for empty lists, which will trigger a Clutter
assert later.
While the list is never supposed to be empty, bugs happen; crashing
users' systems is the least graceful way of handling this, so don't
do it.

Currently we only show/hide the left and right arrows when
we reach the initial/end position. This patch changes this
behaviour by showing the arrows whenever is a scroll is possible.

destroy() checks if we are visible to decide whether to destroy the
actor immediately or after a fade out animation. Since actors are
visible by default it would always end up destroying only after the
animation time.

Due to limitations and bugs in SpiderMonkey's GC, wrapper objects
for cairo contexts and similar may not get cleaned up immediately
after repainting, leading to leaking memory. Explicitly disposing
of such objects after they're not needed can clean up large portions
of memory for cairo surfaces.
