Restore/save configuration-cache data in first action

Previously, the action was restoring/saving the configuration-cache data for each
step that applied the action. In order to support Gradle invocations that are _not_
managed by the action, the configuration-cache restore is now performed in the initial
action step, and save is performed in the final post-action step.

The build root directories are recorded for each invocation via an init script.
