🐞 Android 12: PendingIntent mutability

[tobrun]

When targeting Android 12 as target SDK and including mapbox-events-android. We are hitting an IllegalArgumentException, this is because pending intents are now required to be tagged as mutable/immutable. For more information see pending-intent-immutability.

Pending intents are used in the AlarmSchedulerFlusher:

mapbox-events-android/libtelemetry/src/full/java/com/mapbox/android/telemetry/AlarmSchedulerFlusher.java

Line 20 in d73ca29

private PendingIntent pendingIntent;

While Android 12 is to be expected to be released by September, we need to incorporate these fixes in downstream projects.
