Add screen_view and screen_leave analytic events

[hamorillo]

Description

This PR adds the properties to the Event class in the analytics module. Also, to verify that it works, I'm adding the screen_view and screen_leave events on the Screen composable.

This way, we can also work in parallel to add analytics, avoiding some conflicts.

Testing Steps

• Verify you can see the events on tracks (you can use the filter gravatarandroid%)
• You can also verify that the event is tracked by adding a flush after each event and analyzing the network requests.

Adding a required screenName parameter is a breaking change to the Screen composable API. Consider making this parameter optional with a default value to maintain backward compatibility, or provide an overloaded function that doesn't require the screenName parameter.

Suggested change

	screenName: String,
	screenName: String = "",

❓ Is that a Track's requirement to prefix all the events?y

[hamorillo]

As far as I remember, yes. In fact, we should use that concrete prefix as it was added to the allow list.
