Switch to anyExpansion to prevent flicker

The legacy implementation of ShadeInteractor#isAnyExpanded
includes logic for how the legacy shade works, which includes
a flicker to 1 and then 0 as the shade expands and collapses.
This was causing the notif scrim to show incorrectly on
ALTERNATE_BOUNCER->GONE

Fixes: 338604230
Test: manual - observe notif scrim alpha during transition
