Change transitions in progress back to a Set

Now that we have modified equals in aosp/1839538 to include the
Lifecycle and SavedStateRegistry, we no longer need a list to track all
of the transitioning entries that don't have instance equality and we
can still maintain the behavior ensured by aosp/1792930.

RelNote: "ViewModels will no longer be destroyed when transitions are
interrupted by navigating back and forth between the same screens"
Test: TestNavigatorStateTest
Bug: 200817333
