Share code between ToolTip and CallTip

[maurerle]

Description of Changes

• this creates a base class for ToolTip and CallTip as they are indeed quite similar
• this should be refactoring only without logic changes
• I did not change the behavior intendently, I changed the ordering in the initialization but otherwise this should not change the behaviour.

One could probably go even further, but I think its a good compromise to deduplicate the code without changing a lot

• Wrote at least one-line docstrings (for any new functions)
• Added unit test(s) covering the changes (if testable)

• Included a screenshot or animation (if affecting the UI, see Licecap)

Issue(s) Resolved

Fixes #9339
