A workaround for ChooserActivity memory leak

Add ScopedAppTargetListCallback class to wrap AppPredictor callbacks
that breaks the callback reference chain when the specified scope gets
closed.

Bug: 290971946
Test: Launch Chooser multiple times in a row, collect heapdump with
a forced garbage collection, verify that:
  * there are no ChooserActivity objects in the dump;
  * there are multiple ScopedAppTargetListCallback instances in the dump
    with AppPredictor$CallbackWrapper in their GC root path.
Test: manual functionality smoke tests: activity configuration changes,
pinning targets (all triggers content reloading).
Test: unit tests
