Show a notification at sync when ContentProvider inaccessible

[sunkup]

Purpose

When content providers like contacts or calendar storage are inaccessible we can not sync and should notify the user about it.

Short description

• extract the notification handling from SyncManager
• send notification when content provider inacessible

Use for testing

adb shell pm disable-user --user 0 com.android.providers.calendar
adb shell pm enable com.android.providers.calendar

adb shell pm uninstall -k --user 0 com.android.providers.calendar
adb shell cmd package install-existing com.android.providers.calendar

It doesn't work for me, I've tried disabling and uninstalling as shown, and no notification is shown.

@ArnyminerZ The notification is only shown upon sync. You need to disable the content provider select collections for synchronization and initiate a sync manually / wait for periodic.

Yup, I was doing that. I tried:

1. Configure an account, and enable some collection with calendar
2. Run: adb shell pm disable-user --user 0 com.android.providers.calendar
3. Synchronize.
4. No notification is shown
5. Run: adb shell pm enable com.android.providers.calendar
6. Run: adb shell pm uninstall -k --user 0 com.android.providers.calendar
7. Synchronize.
8. No notification is shown
9. Run: adb shell pm disable-user --user 0 com.android.providers.calendar
10. Synchronize.
11. No notification is shown

Running on the emulator SDK 35.

You're right. It's because I try to dismiss the notification once the content provider is available again ... Will take a look!

@ArnyminerZ Please take a look now.

Also, I am also wondering whether it's smart/possible to pass the sync data type instead of the authority to SyncNotificationManager - the only issue I see is that we want to show the correct authority in the debug data. What do you think, is it possible? Should go in a separate PR then though.
