Add Experimental APIs for opts out of savedState

Now that navigation supports saving the state for multiple back stacks,
we have made that the default behavior for all of the NavigationUI
helpers. Unfortunately, saving state does not support some deprecated
APIs like retained fragments, which means using them together causes a
crash.

We need to add some experimental APIs that allow developers to disable
saved stated in the short term so that those apps can fix their usages
of deprecated APis and properly save their state.

RelNote: "Added experimental APIs to `NavigationUI` to allow you to opt
out of saving your state."
Test: ./gradlew checkApi
