Simplify config changes and request media host layout updates

- Each QSPanelController* class had its own OnConfigurationChangeListener,
  in addition to an overridable method in the base class that was called
  in the listener - moved the child class listener code into that method
  so there's a single listener registered.
- When reattaching the media host after an orientation change,
  explicitly call setLayoutParams to ensure that a layout update is
  requested
- Add more info about current config to dumpsys

Bug: 198319256
Test: atest com.android.systemui.qs
Test: manual - verify media view looks correct when rotating
