[Gradle] Enable stable configuration cache preview (#119382) (#119407)

The STABLE_CONFIGURATION_CACHE feature flag enables the following:

- tasks using a shared build service without declaring the requirement via the Task.usesService method will emit a deprecation warning.
- when the configuration cache is not enabled but the feature flag is present, deprecations for the following configuration cache requirements are also enabled:
    - Registering build listeners
    - Using task extensions and conventions at execution time
