feature: Add utilities for managing toast queue #1248
Description
Desired capabilities:
- Ability to dismiss toasts from the queue before they have been displayed (see this PR
- Ability to update queued notifications
- Ability to dedupe queued notifications (by toastId)
- Ability to get queued notifications (maybe integrated with useNotificationCenter or as separate utility)
- onChange status for toast being queued
There are some conceptual reasons for this request:
- To enable having a badge attached to the top notification showing the total number of notifications displayed/queued
- To proactively show queued notifications in a notification center, even before they have been visibly displayed to the user as toasts
- To enhance deduping/updating behavior for notifications that are queued
