This needed a bit of refactoring of the ChartItem code, because
we have to be signaled on drag start. Currently only one handle
can be selected at a time. This was (implicitly) the case anyway,
as far as I can tell.

Code is mostly based on the "tooltip item". The dragging code was
slightly reworked to be more logical. A "disk item" was added for
the handles.

This was very painful, because I had to implement rearranging the
paint order of the QSGNodes. The resulting code appears quite
brittle. Let's see where that brings us.

To do so, generalize the animation routine.
This seems to expose a QtQuick bug: we get spurious
hover-events when the tooltip item is updated in the
animation. We have to check for that to prevent
en endless loop (until the user moves the mouse out
of the profile window).

Reimplement a feature that was lost when porting the ToolTipOtem
to QtQuick. This is a bit of a longer commit, because the icon
of the event is now drawn explicitly, instead of using HTML.
This encompasses a UI change: the icon is now the icon shown
on the profile and not a general "warning" icon.
This commit also fixes update of the tooltip when panning the
profile.

Still behaves weirdly when panning the chart.
No support for moving the ToolTipItem.
Doesn't add information on bookmarks under the mouse cursor.

It would be nice to have a single "any setting changed" signal and
not to have to listen to all of them individually...

This feels quite a bit slower than the non-QtQuick version. This
makes sense, as there is an additional level of indirection. Instead
of painting directly, we paint into an QImage and turn that into
a QSGTexture.
Ultimately one would think that we should render directly using
QtQuick. Alas, we can't, since that would mean no more printing/
exporting of profiles. How sad.

This breaks all dynamic features, including animations,
zooming tooltips, planner-handles, etc. They will have to be
converted one-by-one to QtQuick, which will be a major pain,
as the ProfileView is destroyed by Qt6 on reparenting.
This means that the view cannot store any persistent state.
