RUM-7528 Introduce the setLastInteractionIdentifier Public API

[mariusc83]

What does this PR do?

Following the RFC we are introducing the setLastInteractionIdentifier API as part of the RumConfiguration#Builder in order to provide external control on which action intercepted on the previous view will be considered as the last interaction leading to the next view needed in the interaction-to-next-view metric computation. The default identifier being used is a TimeBasedInteractionIdentifier with a default threshold interval of 3000ms. More about this you can read in the class docs in the PR itself. This could be re - used by our users in the Configuration Builder by changing the time interval to their internal needs.
