6a46d338e7 extensions: Provide separate implementations
For the time being this mostly means re-exporting functions
from the shared module. However openPrefs() is now only
available to extensions, and we stop exporting both
getCurrentExtension() and setExtensionManager() to either
extensions or prefs.

d3f662fbf2 extensionUtils: Split out extension convenience functions
ExtensionUtils was originally used for shared functions between
the extension system and the (old) prefs-tool, but then gained
useful API meant for extensions themselves.

It's a bit weird to mix the two, so split out the extension convenience
API into a separate module.

We will soon split up the module further, and add specific "flavors"
for extensions and preferences, with the current code providing a
shared base for both.

That should explain both the new location and the odd module name. :-)

83c08e17cf dbusServices: Refactor service utilities from fileUtils into dbusUtils
To enable porting services to ECMAScript modules independently of
the shell, split DBus service utility functions into a new file,
dbusUtils.js

ae92c1c4eb dbusServices/extensions: Split error page from window
The error UI comprises the bits that are actually custom. Splitting them
out from the off-the-shelf window makes it easier to replace the dialog
with libadwaita's dedicated preference window.

073dbc3a04 dbusServices/extensions: Split out prefs dialog
We're about to make changes to the UI, so this seems to be a good
time to split GUI and service code.

23e5cd4e10 dbusServices/extensions: Include Params module
It's unused and was removed in commit a0467bf875, which broke extensions
that rely on it in their preference widget.

As the removal only happened post-3.36.0, add it back until we branch.

34e85342d8 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.

91b7474d5a 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).
