Android:Coin: do gradle build in provisioning to cache downloadables

If Gradle is not present in the system, it's downloaded from the URL
from the Gradle wrapper. Also, the same for AGP when an Android
project build is done. Currently, that's done on every integration,
and that can be unreliable due to networking flakiness. With this
patch, a Gradle build is done once during provisioning where the
downloads of Gradle and AGP dependencies are downloaded.
