profile: implement "empty state" in desktop's ProfileWidget

Browse source 
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.
