Whiteboards as a separate search result

[hero101]

Description

Currently if a Whiteboard is matched in a search query, the containing it Collaboration tool is returned instead of it.
This behaviour is more unclear when the Whiteboard is contained in a Tool of Whiteboards, so the Tool with all Whiteboards is returned instead of that single matched Whiteboard.
Some workarounds are also introduced in the code to cover this behaviour, which makes things complicated and fragile.

As a user
I want to have the whiteboards as a search result
So that I have the correct Whiteboard returned instead of the Callout which contains it
