Make incoming call screen style configurable. (2/3)

Change-Id: I46db78c9b48fae52530b96789ec2721d51b7185a
Avoid layout changes on call disconnection.

This avoids showing the call buttons when an incoming call is
disconnected remotely while still ringing, which in turn avoids an ugly
transition when using the full screen caller photo.

InCallUI: add Incoming Call Background (1/2)

last week, as we know we have bug with non-Intrusive Incall on Back pressed
and we already fix that by disabled Back pressed while non-Intrusive InCall enabled

instead disabled Back pressed, this patch introduce non-Intrusive Incall will go to background mode
using Notification on Statusbar

Based on SlimRoms patch
https://gerrit.slimroms.net/1857

with changes to follow Intrusive Incall

ps5 - allow flip actions while call is in statusbar/notification area (background)
    - show the navbar so devices without hardware keys can actually have the back
      button there
