Is your feature request related to a problem? Please describe.

WPF implements attached ToolTipService.ToolTipOpening and ToolTipClosing events that are AddOwner-ed on FrameworkElement, thereby adding FrameworkElement.ToolTipOpening and ToolTipClosing events and related OnToolTipXXX methods on elements.

These events are handy, especially the opening one, because it allows a tooltip to be customized prior to display or alternatively canceled. The customization ability is a feature we could use.

Describe the solution you'd like

Make a similar design to WPF, at least in terms of adding the two events on Avalonia's Control class so that we can customize or cancel tooltips prior to display. And the ToolTipClosing event is there as well in case people need it for some kind of cleanup.
