This change will update the UI and internal reference names to use
the "Desktop Sharing" term, which refers to sharing a user's screen
with remote connections.
This differentiation is being introduced now so that we can avoid
conflict with "Remote Session", which will refer to headless/dedicated
remote desktop sessions.

Let's not show the page neither crash when there are issues with
finding the remote desktop gsettings in the system, or when the
RemoteDesktop name didn't appear on dbus.

Row subtitles in Settings are typically a description of the main label or setting.
You can see this in Mouse & Touchpad, Privacy, Sharing, and Wi-Fi.
For the System panel we did something a bit different and used the subtitle to show
the status of each panel.
Given the standard use of subtitles elsewhere, this feels a bit surprising which,
as a result, makes the panel harder to read. I think that a standard description
would probably also be more useful than the current labels.

This also removes the thin CcSystemPage abstract class because it was
only introduced to add the support for dynamic System row subtitle. Now
this abstraction is no longer necessary.

Move the page description to AdwPreferencesPage, since
it's the correct place to put the page description.
Also, set up the page description in the C code to
help translators.

So that the main switch and the page summary are updated when the
backend changes.
With this, the UI reacts to external calls such as
`grdctl rdp enable`.
The Remote Desktop page subtitle was updated asynchronously when
the System panel was loaded but after the following steps:
1. Connection established to `org.gnome.SettingsDaemon.Sharing`
(handled on `sharing_proxy_ready`).
2. Then a check whether Remote Desktop is available by watching
the `org.gnome.Mutter.RemoteDesktop` bus name appear.
3. Then we are finally populating the UI (and updating the
subtitle).
Now we bypass the panel initialization and check directly for the
"enable" state of the backend GSetting and the availability of the
gnome-remote-desktop.service, using `is_remote_desktop_enabled()`.
Fixes#2772
