[notifications][android] Add sticky property to notifications

[barthap]

Why

Implements changes proposed in #9302.

Current Notifications API provides autoDismiss property, which directly corresponds to autoCancel on Android - it specifies if notification can be dismissed by tapping it, however it can be dismissed by swipe. Android API can also set notification as ongoing - it can be dismissed by tapping, but not by swiping.

Expo legacy notification API had this property available, but it was replaced with autoDismiss in the new API.

How

Added sticky property to NotificationContentInput interface, used by local notifications. On native side - added it to NotificationContent.Builder where needed and connected it with Android's setOngoing().

Test Plan

• Test local notifications
• Test FCM push notifications*

* Note: Push notifications JSON payload doesn't contain sticky and autoDismiss properties, however JSONNotificationContentBuilder is handling them correctly - default values are set.
