This PR is about updating the operating system to macOS-12 as the previous one was going to be deprecated, as well as updating the checkout to v3 to avoid the warnings in the panel; adding setup SDK action to accept the license which was missing from the beginning.
I also added imports instead of adding them directly with the codes.
As a reference, there was another PR with a similar topic, but it wasn't complete: #483
Introduce Gradle Managed Device definitions to modules that have instrumented tests.
At the moment, defining it as a convention plugin isn't possible due to the bug. That bug is now fixed and will be included in Android Studio Flamingo.
Once Flamingo becomes stable, convert the GMD definitions as a convention plugin (#523)
