Notify StateManager of workspace reveal animations.

This way any subsequent state changes during the animation will
cancel it. Previously swiping up to All Apps immediately after
going home would cause the 2 depth animations to interleave,
ending with a depth of 0, for example. Now the workspace depth is
cancelled and the All Apps depth is correctly applied.

Fix: 405836159
Test: Manual (swipe home and immediately to all apps)
Flag: EXEMPT bugfix
