Oilpan: merge MIDIAccessInitializer's prefinalizers.

As the prefinalizer handling does not support having multiple prefinalizers
per object, combine the MIDIAccessInitializer + LifecycleObserver
prefinalizers methods into one, and arrange for it to be the prefinalizer
for MIDIAccessInitializer.

In the event this manual prefinalizer re-combination turns out to be a
common pattern and workaround, we will revisit the restriction of allowing
only one prefinalizer registration per object.
