What's new in this PR?

User needs to be informed of the actions taken towards them by the moderator/admin during the call.
Managing and storing these events has been added in kalium, along with the use case to observe them.
This PR includes changes needed to display them correctly:

• Added two methods to ExpiringMap to be able to add item which expires in a given custom period and to add one without expiration
• Added new InCallToast model which currently has two main types:
  • ModerationAction to show all actions done by the moderators/admins
  • Fullscreen which handles already existing labels informing about how to open or close the fullscreen
• Added logic of observing and expiring toasts in OngoingCallViewModel - toasts are stored by their ID, but currently toasts of the same type share the same ID, thanks to that there is always only one toast of a given type on the screen, and when a new one appears, it overwrites the existing one of the same type
• Created dedicated composable and panel to show these in-call toasts chronologically and animate adding and removing them
• Removed old DoubleTapToast and its usages in FullscreenTile and OngoingCallScreen as it’s now handled by the InCallToast
