Use task avoidance API in gradle scripts (elastic#11914)

* Use task avoidance API in gradle scripts

This commit uses the task avoidance api (tasks.register vs task.create/
task DSL), as recommended since Gradle 5.1

This should reduce the execution of unnecessary tasks in build jobs, and
hopefully improve build resiliency and execution time.
