[AND-373] Filter-out unneeded notification updates and add flag to enable/disable

[liviu-timar]

🎯 Goal

Ongoing call notifications are updated when the number of participants changes. We have three cases: no remote participant (shows generic info and icon), 1:1 call (shows the name of the other participant and avatar) and multiple participants (shows Group call text and icon). More info in this PR.

🛠 Implementation details

• Debounced notification updates caused by participants joining/leaving, when the count falls in the same multiple participants case. Useful for calls with a large number of join/leave events, e.g. livestreams.
• Checking if the participant count change is still in the > 1 case. If yes, don't update the notification.
• Update the notification only when the participant count changes from multiple to one or none and vice-versa.
• Added notificationConfig.enableCallNotificationUpdates flag to disable notification updates in StreamVideoBuilder.
