Reset sticky navbar timeout when rotate btn shown

First revealing the navbar and then rotating in an
immersive sticky activity makes the rotate navbar button
hard to tap. Signal to the navbar to reset sticky hiding
timeouts if the button becomes visible or changes.

Change-Id: I381bbfd2e0192465b8358bedd213f23dde8ec982
Fixes: 78248328
Test: manual testing with custom immersive sticky activity
