Run body of applyTopology for all non-noop drags

In onBlockTouchUp, if DisplayTopology.rearrange happened to revert the
change made by the drag so that it matched the before-drag layout, the
blocks would not be moved, so the block would be in the dragged position
but not the normalized position.

This will happen when rearrange has a bug or is otherwise optimizing the
layout, which is dependent on the implementation of rearrange.

The test field mTimesReceivedSameTopology has been replaced with one
that represents an observable positive operation:
mTimesRefreshedBlocks, the validation of which has been added to some
existing tests.

Flag: com.android.settings.flags.display_topology_pane_in_display_list
Test: move display so that rearrange reverts the change, then exit and re-enter the external display fragment, and verify it matches the state when left
Test: DisplayTopologyPreferenceTest
