Now that extensions themselves are imported as modules, do the
same for their preference dialogs.
Extensions must now export a class with a `fillPreferencesWindow()`
method as default.

We want to replace gjs' custom (and now legacy) imports system
with standard EcmaScript modules: JS developers are already
familiar with them, they have better tooling support and using
standard features over non-standard ones is generally the right
thing to do.
Our D-Bus services are separate from the main process, and thus
can be ported separately (except for the few imports that are
shared with the main process' code base).

ES modules do not allow exports to be overriden, in anticipation
of the ESM port add a `setCurrentExtension` utility which will
throw if used in the shell. This is tested using a conditional
import of Main.

The current preference API - buildPrefsWidget() - predates client-side
decorations. While extension authors have been finding ways around
the limitation of not having access to the window/titlebar, the change
to the new Adwaita API seems like a good time for an updated API that
officially provides that access (as far as allowed by libadwaita).

Adapt the new GNOME platform API for the upcoming 42. This makes
sure that we get the latest version of the stylesheet, as well as
support for the new dark mode.
Using the dedicated preference API also gives extensions with more
complex preferences an easier and standardized way for implementing
multi-page preferences.

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.
