Currently, the zoomLevel is reset for every plotDive() call,
because the zooming is done via the QGraphicsScene. However,
this does not work well (e.g. axes are likewise zoomed) and
in the future a change of the zoom level will cause a replot.
Thus, remove the zoom-reset in plotDive() and do it explicitly
when switching dives.

This finalizes the split between interactive (ProfileWidget2)
and non-interactive (ProfileScene) parts of the profile.

The mode of the profile (profile, edit, plan) was set in
MainWindow and ProfileWidget. For consistency move the one
setProfileState() call from MainWindow to ProfileWidget.
This removes a direct access to the profile-view and
therefore improves encapsulation.
Also, clear the profile, when no dive is shown to remove
any potentially dangling references.

The profile has an "empty state" showing the subsurface logo,
which is active when no dive is selected.
Switching to/from this mode is quite complex, because all the
chart features have to be hidden/shown, etc. Moreover, this mode
is not needed on mobile, where multiple ProfileWidgets can
be active at the same time and every dive has at least a
"faked" profile.
Therefore, implement this mode directly in the desktop
version of the widget. This makes the rescaling distinctly
less cumbersome. It is implemented using a QStackedWidget,
which switches between the profile and the logo.
This commit does not remove the empty state from the profile.

Not having to readjust the scale on-demand will make the
code distinctly simpler. Let's just pass it once.

Create a new class that encapsulates the profile-widget UI.
This is called ProfileWidget, which might be confusing since
the actual display is called ProfileWidget2. However, the
plan is to rename the latter to ProfileView. After all, it
is also used to print and to show the profile on mobile.
