According to the most recent mockups [1], when Airplane
Mode is switched on, the Wi-Fi connection will be turned
off and the Wi-Fi panel should show an empty state for
Airplane Mode. This is currently not implemented in the
codebase.
This commit adds an Airplane Mode empty state for the Wi-Fi
panel, and a small logic adjustment to show it under these
circumstances.
The current Wi-Fi panel ties the Airplane Mode row to the access
point list of a given Wi-Fi adapter. That has unintended but
bad side effects: when enabling Airplane Mode, the row disappears
and we have to switch to another panel (e.g. Bluetooth) in order
to disable it. This is functionally wrong: we should be able to
enable or disable Airplane Mode from where we initially changed
it.
This commit reorganizes the widget hierarchy in order to put the
Airplane Mode row outside of the main GtkStack page. This is
necessary in order to fully implement the proposed mockups[1]
and, in general, because it's the right thing to do.
Notice that the logic of the empty states in [1] is not fully
implemented yet; this commit only reorganizes the widgets that
already exist to get closer to the mockups. Subsequent commits
will implement more of the empty states.

This commit renames {network|wifi}.ui to cc-{network|wifi}-pane.ui,
in order to match the corresponding C files. This introduces no
functional changes.
