[Chipbar] Remove the media-specific wake reason and window title from

the ChipbarCoordinator and instead pass them in each time we display a
temporary view.

Now, TemporaryViewDisplayController needs to handle different
information being displayed with different window titles. That logic has
been added and tested.

Bug: 245610654
Test: manual: Verified that media ttt views still display correctly
Test: manual: Verified that showing a new media ttt view with a new
title will animate out the old view and display the new one
Test: atest TemporaryViewDisplayControllerTest
