Start rewrite of tooltip

ToolTipProxy is now a QQuickWindow and renamed to ToolTipWindow.
This is done in C++.
ToolTip itself is a QML file, which internally uses tooltipwindow to
display the attached item.

Basic showing / hiding and embedding an Item works, positioning,
margins, etc are not implemented yet. Neither are special windowmanager
hints and flags.
