Some default values differ between classic and normal sessions. We
used to implement this by overriding the shell's default values in
mini-extensions (or more precisely: reversing the shell's overrides).
Use a mode-specific overridesSchema instead, which has the advantage
that settings defaults will not change unexpectedly when extensions
are disabled/enabled (for instance during screen locks).

When the number of workspaces changes, we clear the existing menu
and recreate it based on the screen::n-workspaces property, so it
is slightly more correct to track changes to the property directly
instead of using the workspace-added/workspace-removed signals.
This change also fixes a corner case, where changes to the property
before workspaces are initialized are missed and we end up with the
wrong number of workspaces.

In addition to "always" and "never", gnome-panel supported an "auto"
grouping mode, which only started to group items when running out of
available space. It makes sense for us to support the same option in
the window-list extension, so implement it.

-st-natural-width is useful to request a larger-than-usual width,
add back the max-width removed in commit 702cf52cfc to also request
a smaller-than-usual width as necessary.
Items in the window list should take up a fixed amount of space
unless the list is full and items need to shrink. To achieve this,
replace the max-width with the newly added -st-natural-width.
