We currently ignore any error that may occur when calling the
OpenExtensionPrefs D-Bus method. Right now such an error is highly
unlikely, given that we already checked that we are running under
gnome-shell and the extension in question exists and has prefs.
We'll soon make sure that only one dialog is shown at any time,
which is an error that we can realistically expect, so handle that
properly.

For the prefs command, we first fetch the extension info to check
whether the extension exists and actually has preferences. This
pattern can be useful for other commands and properties, so split
out a generic helper function.

Error reporting is useful when used interactively, but often undesirable
when used in scripts. Account for that with a common --quiet option,
which is more convenient than redirection stderr to /dev/null.

The gnome-extensions tool code is really independent from the rest of the
code base, and could be used either as part of the gnome-shell build or as
stand-alone project (for example for the extension-ci docker image).
We can actually support both cases by moving the code to a subproject.
