Add mnemonics to Users and About rows.
Also, fix the mnemonic of the Remote Desktop
row, which was using the same letter that
the Region & Language row uses.
This moves the UserAccounts panel to a page in the System panel.
This simplifies a lot of the existing code in the UserAccounts panel.
I did minimal changes to the sub dialogs so that those can be touched
in following changes, making it easier to review this one alone.
The main panel widget is now CcUsersPage, and is an AdwNavigationView
widget that has a default "current_user_page" page. Each page is a
CcUserPage (careful with the one-character difference between these
two classes).
Each CcUserPage has an associated ActUser object.
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.
