[backport 7.x]Move retrieval of Stack version from Gradle's configuration to execution (#13042) (#13066)

The Gradle's configuration of task should be as fast as possible and don't break the build.
This commit moves retrieval of Elastic Stack version from the remote registry to the execution phase of the tasks.
Also the tasks that depends on this has received the same change (downloadEs and check EsSHA), moving from configuration to execution phase.

Close #13030

(cherry picked from commit cef339ce57)
