Add Callout/Tooltip to MRTK 3

[alexapropt]

This issue has been migrated a new MRTK repository, and the status of this issue will now be tracked at the following location:

• https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity/issues/205

---

Overview

The tooltips are an excellent tool, but we are still forced to use those from the MRTK2 version, as there is no option in MRTK3, as far as we know.

Tasks

• [ ] Add Tooltip component and prefab(s)
• [ ] Add Sample scene using Tooltip

Hey! Just to clarify, are you referring to these sorts of tooltips? https://learn.microsoft.com/en-us/windows/mixed-reality/mrtk-unity/mrtk2/features/ux-building-blocks/tooltip?view=mrtkunity-2022-05

Or these popups when you hover something to provide additional contextual info, like speech commands https://learn.microsoft.com/en-us/windows/mixed-reality/mrtk-unity/mrtk2/features/input/speech?view=mrtkunity-2022-05?

Hello! Sorry for the delay in replying. The question is really about the 1st option. I'm using the MRTK2 option mixed with MRTK3 to provide information to the user during procedures. Voice commands is another matter :)
