Correct errant entry in to DRAG_RESIZE_FREEFORM state.
Observing the logic in computeDragResizing(), we see that whenever an
AppWindowToken has frozen bounds we will enter the drag resizing
state. Furthermore, in setDragResizing() we see that if the docked
divider is not resizing, then we set ourselves as freeform
resizing. Also observe that AppWindowToken#startRelaunching
unconditionally freezes the bounds for tasks not in the freeform
stack. This means we are almost always entering the freeform resize
state while relaunching. Within computeDragResizing, the StackId check
and the MATCH_PARENT check have prevented this from being an issue in
too many places, espescially in pinned.
Once we are in this state, calculateSurfaceBounds() will force us to
0,0 as it thinks we are using the big surface approach.
There's no need to freeze the bounds if we weren't drag resizing at
the time that the app is relaunched, and this CL enforces that.
Bug: 62430780
Test: Manual repro from bug. To verify no regressions, create app with long delay in onResume (>1s) verify no flickers when releasing the docked divider and triggering a resize.
