breakManager: Add new state machine for screen time/health breaks

Browse Source 
This implements health break reminder support in gnome-shell. It depends
on a
few bits and bobs from other modules:
 - New settings schemas in gsettings-desktop-schemas (released in
   47.beta, which Mutter already depends on)
 - A settings UI in gnome-control-center
 - User documentation in gnome-user-docs

It implements the design from
https://gitlab.gnome.org/Teams/Design/settings-mockups/-/blob/master/wellbeing/wellbeing.png.

The core of the implementation is `BreakManager`, which is a state
machine which uses the Mutter `IdleMonitor` to track whether the user
is, or should be, in a screen time break.

The `BreakDispatcher` is based on top of this, and controls showing
notifications, countdown timers, screen fades, the lock shield, etc. to
make the user aware of upcoming or due breaks, as per their notification
preferences.

Unit tests are included to check that `BreakManager` works. These
provide mock implementations of basic GLib clock functions, the
`IdleMonitor` and `Gio.Settings` in order to test the state machine in
faster-than-real-time.
