Disable ActionBar usage of transitions

Disable ActionBar usage of transitions

Various artifacts across apps were coming from ActionBar's use of
the new transitions framework. Disabling transitions for now to get
things back to a more stable state.

Also, fixed some related bugs in transitions themselves, including
a change in TextChange to account for text selection, which was causing
errors in Keep's SearchView.

Issue #10860557 TextChange animator may old stale value
Issue #10819685 sometimes icons are lighter
Issue #10750525 Share and Settings icons overlap when stopping slideshow
Issue #10839551 Sometimes the search text box is right-aligned in Keep
Issue #10727484 Cursor incorrectly positioned after entering first letter during search action in keep app
