[Status Chip] Fix local card migration icon highlight

Previously the icon did not set highlight ink drop animation correctly
that it did not go through Button::SetHighlighted(bool). It is needed
because the status chip container is a button observer which observes
button highlight state changes, and then update its own highlight status.
This is only triggered by SetHighlighted().
