Remove ToastPresentation usage and use toaster to display messages

[veekeys]

Added iTwinUI toaster to display the toasts.
Returned old implementation on message components to get rid of ToastPresentation and marked them as deprecated.
Added new function to register ref to animate iTwinUI toasts to.
Added few deprecated tags as suggestions to some of managers. If we agree to all these deprecations (there might be more), I'd like to also add text in jsdoc about using toaster to display toasts where relevant.

Vykintas, this does not hook the toaster into the MessageManager -- MessageManager.outputMessage does not open any toasts. Is that still in progress or just broken?

Where have you found it's broken?
outputMessage has this 'ifs' carousel, which changes types or shows some other messages:

and then at the end it is calling addMessage which has the toaster hooked up:

Unless I misunderstood here something..?

I pulled and built the branch and ran ui-test-app. The messages get logged in the message center, but no toast message show up, except activity messages.

Good progress, that should cover most cases where toasts/messages are displayed.
As discussed, we need to ensure that ActivityMessage (and other message components) are not used internally (replaced with itwinui toaster for UI consistency). I.e. we probably want to use itwinui toaster in: ActivityMessagePopup, StatusMessagesContainer.
Also, specifically for ActivityMessage we need a component with equivalent layout that's rendered via the itwinui toaster.

@NancyMcCallB @GerardasB Would you mind checking again? I have fully replaced all toasts and added new custom activity message.
In component examples toasts are not visible, because iui-toast-wrapper is having too low z-index (edit that through console to see them).
THere is already new iTwinUI version with z-index fix, I just need to update here. Will creae a separate PR for this, I think.

If this approach looks ok, I will need to update with better description and maybe move files around?

This helped! Thanks!
All of this should be in documentation, IMO.
