extensionSystem: Add method for opening extension prefs
Extension that want to expose their own preferences (for example as menu
items) do that by passing their UUID to gnome-shell-extension-prefs.
But since 3.36.1 the app is optional and no longer accepts arguments on
the command line. To adjust, extensions now need to make a D-Bus call
the extensions portal, just like the app and gnome-shell.
We will add a convenience method for that purpose, so it makes
sense to share the existing code. As it's extension-related, the
extension manager looks like the right place ...

js: Account for promisified call() method
A promisified method expects the callback parameter to be either
a function (in which case the original method is called normally)
or omitted altogether (in which case a Promise is returned).
The call to open application details in Software does neither and
passes null instead, which will result in a warning (because no
function argument means a promise will be used, but not omitting
the parameter means we end up with too many arguments).
The app-cache code currently stores the folder translations in a hash
that can be accessed via shell_util_get_translated_folder_name().
This hash uses the filename (inc. extension) for the "desktop-directory"
as key which causes an issue when trying to find the translation
on AppDisplay._findBestFolderName() which gets categories (folder names)
from the app info which doesn't contain the ".directory" extension.
Fix that by storing the filename without extension as the hash key for
the cached folder translations.

main: Don't override DesktopAppInfo desktop if already GNOME
During the shell initialization we call the (deprecated) function to
override the Desktop environment in Gio DesktopAppInfo to make sure that
applications are correctly shown (as per commit b2fbf5a2), however this
might break the cases in which $XDG_CURRENT_DESKTOP is already set and
contains GNOME (given that is now a list).
In Ubuntu this is in fact set to: ubuntu:GNOME.
Now, if an application contains NotShowIn=ubuntu, the key will be ignored by
the shell, and the application is still listed everywhere.
So, override the DesktopAppInfo desktop environment only in the case that
the current desktop is not already GNOME.
At the current date I think we could just safely get rid of this override at
all, but there could be still cases where it still might be useful, like when
running as nested in some other environment, so keeping it.

appDisplay: Don't start animation from the 'paint' signal
Starting the animation from the actor 'paint' signal has various
unwanted consequences, such as sometimes trigger a
clutter_actor_queue_relayout() during the paint phase. One unwanted
consequence was that an offscreen actor effect was disabled during
painting, meaning the effect would begin being active, but later during
the post-paint processing being disabled. The caused said effect to push
an offscreen framebuffer to the paint context, but then just destroy it
instead of popping it. When this happened, we'd end up trying to operate
on a framebuffer that may had been finalized, or not, depending on the
garbage collector. Sometimes, for some users, this caused a segmentation
fault when trying to pop a matrix from the framebuffer matrix stack.
Deal with this more properly, by using the 'view-loaded' signal to wait
with animation until the view is loaded, as well as using MetaLater to
schedule the start of the animation.
For when a view was signalled to be ready, we're in a state where we can
start animation before the next frame as the layout is ready, but when
not, we have to add back the "hack" where we must wait for one frame for
the target icon positions to be up to date. Do this by adding a
MetaLater IDLE callback that starts the animation *after* the next
frame. This also needs the old 'opacity = 0' work around to not show an
incorrect first frame.

extensions-tool: Use new Extensions proxy
While sandboxing isn't a concern for the gnome-extensions command line
tool, using the Extensions proxy directly means that D-Bus methods are
called from the tool rather than gnome-shell, which allows the proxy
to auto-shutdown when done.

extensionPrefs: Use new Extensions proxy
We will soon sandbox the application, so it makes sense to not request
more access than strictly necessary (even with priviledged access like
extension management).

dbusServices/extensions: Take over prefs dialog from app
As outlined earlier, in order to turn the Extensions app into a properly
sandboxed application, we need to split out the extension prefs dialog
and move it elsewhere.
With "elsewhere" being the new Extensions D-Bus service, effectively
turning it into a shell extensions portal.

dbusServices/extensions: Proxy Extensions API
Similar to the previously added org.freedesktop.Notifications proxy,
this exposes the org.gnome.Shell.Extensions API and forwards any
request to the real implementation in gnome-shell.
The motivation differs though: We want to be able to package the
extension app as flatpak and distribute it separately, but the
extension prefs dialog is hard to impossible to sandbox:
- filenames need translating between host and sandbox, and we
can only do that in some cases (serializing/deserializing
extensions), but not others (extension settings that refer
to files)
- system extensions install their GSettings schemas in the system
path; the best we can do there is assume a host prefix of /usr
and set GSETTINGS_SCHEMA_DIR in the flatpak (eeks)
- extensions may rely on additional typelibs that are present on
the host (for example because gnome-shell itself depends on
them), but not inside the sandbox - unless we bundle all of
gnome-shell's dependencies
- if gjs/mozjs differ between host and sandbox, extensions must
handle different runtimes for the extension and its prefs
And all those issues occur despite a very permissive sandbox (full
host filesystem access, full dconf access, full org.gnome.Shell
access (including Eval()!)).
This new service will give us an alternative place for handling
the preference dialog:
- it runs outside of gnome-shell process, so can open windows
- it runs on the host, so the extension's prefs get to run
in the same namespace as the extension itself
That is, the service will provide portal-like functionality (albeit
not using the org.freedesktop.portal.* namespace, as extension
management is an inherently privileged operation).

extensionPrefs: Stop handling UUIDs on the command line
We are jumping through quite some hoops to support showing only the
preference dialog when given a UUID on the command line.
As gnome-shell is about to stop calling out to us for the prefs dialog,
the reason for supporting this is going away, so remove all the special
handling.
