Notify Event FMQ when sensor events are read

Notify the Event FMQ whenever sensor events are read by the framework.
This allows for the HAL to utilize the MessageQueue::writeBlocking
function when writing sensor events to the framework.

Bug: 111070257
Test: Verified that the default implementation blocks if the Event FMQ
      is full until events are read by the framework.
