d52b23dec3 switcherPopup: Improve modifier-less keybinding navigation
Commit c899453800 lifted the requirement of switcher keybindings
to contain a modifier, however it is currently only possible to
finish it by letting it time out.

Improve that by also accepting space/enter key presses to confirm the
selection immediately.

998fe58482 switcherPopup: Use roundtrip time when the popup is modifier-less
The noModsTimeout obviously finishes inside a timeout callback, which
means `global.get_current_time()` might return Clutter.CURRENT_TIME (ie.
0) when called inside it, because it's not called while handling an
event. This means when switching apps or activating a window, the
timestamp passed to `activate_window` may be 0, which is the reason why
the altTab switcher is currently broken when using modifier-less
keybindings.

Fix that by using `meta_display_get_current_time_roundtrip`, which
always return a valid timestamp, instead of
`shell_global_get_current_time`.

9132063b87 switcherPopup: Show immediately on second key press
We slightly delay showing the switcher popup to avoid flashing it
briefly in the common case of quickly switching back-and-forth
between two windows.

However some users perceive this delay as slowness. Address this by
showing the popup immediately when another key press is consumed
(that is, a key like Tab is pressed).

0846238f69 js: Use implicit animations for animatable properties
We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:

 - they run entirely in C, while Tweener requires context switches
   to JS each frame

 - they are more reliable, as Tweener only detects when an animation
   is overwritten with another Tween, while Clutter considers any
   property change

476816732f cleanup: Use milliseconds for animation times
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.

In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.

14d7897a93 style: Stop using braces for single-line arrow functions
Braces are optional for single-line arrow functions, but there's a
subtle difference:
Without braces, the expression is implicitly used as return value; with
braces, the function returns nothing unless there's an explicit return.

We currently reflect that in our style by only omitting braces when the
function is expected to have a return value, but that's not very obvious,
not an important differentiation to make, and not easy to express in an
automatic rule.

So just omit braces consistently as mandated by gjs' coding style.

55235c2552 style: Avoid trailing commas in array destructuring
When destructuring multiple return values, we often use trailing commas
to indicate that there are additional elements that we are ignoring.

There isn't anything inherently wrong with that, but it's a style that's
too confusing for eslint - on the one hand we require a space after a
comma, on the other hand we require no space before closing brackets.

switcherPopup: Bind to the stage, not the monitor
The switcher popup is a large, mostly transparent actor that
should cover all the clickable area of GNOME Shell. In Clutter
terms, it should cover the whole stage.

By binding it to the primary monitor, the Alt+Tab behavior
becomes a bit inconsistent. For example, by not hiding when
clicking at empty spaces at other monitors.

Fix that by binding the SwitcherPopup to the whole stage,
and not only the primary monitor.

switcherList: Stop using Shell.GenericContainer
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.

switcherPopup: Rename destroy() to fadeAndDestroy()
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().

is already provided by Function.prototype.bind() - in fact, Lang.bind()

06f790d86c switcherPopup: Handle removal of items from SwitcherPopup
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.

e94de67bd2 switcherPopup: Ignore implicit enter events when the popup is mapped
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
