Remove root window hierarchy logic from ActivityStackSupervior (40/n)
We eventually want to consolidate root window hierarchy logic into
RootWindowContainer. As a first step towards that we separate
the root window hierarchy logic from ActivityStackSupervior into
a temporary new class RootActivityContainer to make it clear what
we later need to consolidate into RootWindowContainer.
Test: Existing tests pass.
