feat: initialize sdk in parallel

[dylancom]

Description

As a latency best practice, Google recommends not waiting for the loadAndPresentIfRequired callback to complete so you can start loading ads as soon as possible after your app launches.

This PR adds a method that directly exposes the UMP Consent Information without having to wait for callbacks. And so the SDK can be initialized faster if consent was obtained in a previous session.
