Original change's description:
> Bento: AltTabMode: Update highlighted window after switching mode.
>
> Regardless of where the highlight position is, after switching
> alt-tab mode, the highlight will be reset to the first or second
> window. This is consistent with highlighting when users first
> enter alt-tab mode:
> - In general case, highlight the second (next) most recently used
> window after the current one.
> - In the special case that the most recently used is minimized,
> highlight itself (the MRU window), so tabbing into it causes it
> to unminimize rather than opening up the next window in the list.
>
> - Track mode switching state in the controller to differentiate
> between normal tab pressing and mode switching.
> - Add Ash unit tests for both cases.
>
> `ash_unittests --gtest_filter=ModeSelectionWindowCycleControllerTest.SwitchingModeUpdates*WindowHighlight`
>
> Bug: 1157100
> Test: Manual test (a video uploaded to crbug) and ash unit tests
