Add env var that forces the vendored caching module when set to
'true', decoupling module selection from the Develocity access key.
Set it centrally in init-integ-test so all tests use the vendored
module by default.
Add a dedicated legacy caching integration test that overrides the
env var to 'false' to verify the legacy module works correctly.

Removes support for configuration-cache extraction and restore from the
caching workflow and related source code. Configuration-cache support
only worked for a limited set of projects (gradle/actions#21), and we
plan to reimplement this properly as part of the
`gradle-actions-caching` project.
The main impact is simplification of the caching logic, focusing only on
common Gradle artifacts. The `ConfigurationCacheEntryExtractor` class
and related logic were deleted from
`sources/src/caching/gradle-home-extry-extractor.ts`.
