[cr142][Android] New arg navigationFulfillmentTypeSupplier at LocationBarMediator.ctor

Chromium change:
https://source.chromium.org/chromium/chromium/src/+/2747c27c571886bc1a646c4ab9eb1fa46c4b29fd

	Use event-driven supplier for fulfillment type

	Replace the polling-based `isUsingAiMode()` method with an event-driven
	`ObservableSupplier` that reports the `NavigationFulfillmentType`.

	This refactoring allows consumers like the LocationBar and Autocomplete
	systems to react dynamically to changes in the fulfillment mode (e.g.,
	switching between DEFAULT and AI_MODE) without needing to continuously
	poll for the current state.

	As a direct benefit, the LocationBar now observes this supplier to
	hide the Lens button when the fulfillment type is AI_MODE, ensuring
	the UI accurately reflects the available actions.

	Bug: 436888404
