fb: navigationbar use always slimactions and add contentdescription

No need to use the AOSP implementation at all...we can send all actions
over SlimActions....so remove AOSP implementation and clean up

As well add contentdescription for accessibility events like talkback
for ppl who are not able to see. Gives the user all information back
needed.

SystemUI: fix wrong statusbar background.

If we turned off screen while some panel was visible than
background of PhoneStatusBarView will not be updated because we receiving single
panelExpansionChanged call and after super.panelExpansionChanged mFadingPanel
will be null (onAllPanelsCollapsed cause this).

Allow updating background when mFadingPanel is null.
